  1. Further information: For sale, a one of a kind 4 channel out Cabernet Dual 6SN7 preamplifier. This is ideal for biamp situations or people with subwoofers they want to correctly drive with line level inputs as there is complete isolation between the two sets of outputs as they have their own separate gain stages. See: http://www.supratek.com.au/ and note normal pricing there is in USD. The Supratek preamps are extremely good value being locally made in Australia, and every single one is a custom build from scratch with the customer's unique requirements in mind. This particular one was built in Jan 2018 and sent back to Mick originally because the high gain of my power amps made for significant hum, leading to a complete redesign of the gain stages, and he blogged on this particular change here: http://supratekaudio.blogspot.com/2018/03/were-back.html This upgraded version is extremely quiet by comparison. Their sound has been described as "beguiling" with one of the finest midranges at any price, exceptional 3D imaging and body, and excellent microdynamics. This model does NOT have a warm romantic sound, but are a tube roller's dream with a 5AR4 rectifier, 6SN7 based gain stages, two completely separate 6L6GC regulated power supplies for each channel, a two box unit with the power supply separate from the gain stages, balanced as well as unbalanced inputs and outputs, separately adjustable gain for the two sets of outputs, and a rudimentary remote control (note the on/off button on the remote control is to turn off the remote control, NOT the preamp.) Included in the price is a set of high gain, low noise, low microphony, matched 1970s NOS Sovtek 6SN7s with less than 200 hours on them, a spare new 5AR4, solid state rectifier (for emergency use only), 7581As as alternative power regulator tubes, and the Herbie's dampers as seen in the images. All original packaging is included, and I should be able to road freight it to any major centre in the country. Photos: Note, there are NO scratches on the chrome, it's just very difficult to get it completely dust free for a photo and the camera shows every little spec of dust.

  3. Hi everyone, I introduced myself from England when my 2009 Supratek Sauvignon arrived: It took me a few messages to MIck and others to work out what all the switches do as the handcrafted "manual" has several omissions/errors: Left and right gain switch directionality: obvious in use of course Mute switch rear centre not mentioned Most significantly I thought I had a failed input as the Tape Record and Tape Play connectors are the opposite way round to the diagram Anyway all is up and running and sounding rather fine. Q1 Remote: the remote was not working. I changed the batteries, followed the reprogramming steps but I still cannot change the volume remotely. The light flickers on the remote as you'd expect. Am I missing a clever trick or is my remote control module in the amp suspect? Q2 Phono stage: there is reference in the manual to the sensitivity of the phono stage. As far as I know I don't have one... Does anyone else? I know the manual is pretty generic but there is no "where fitted"... Q3: Gain settings: would it be correct to call the top-mouned switches "coarse adjustment" and the rear 6-position knob "fine"? I can hear a difference between vertical and the next but not with any further turns. I am happy with how mine is set up, just curious. Many thanks, Nigel

  6. Item: Supratek Grange Pre-Amplifier Location: Melbourne (Sunbury) Price: $6,000 Item Condition: Very Good Reason for selling: Moving up North to an apartment, so everything must go. Payment Method: Pickup - Cash, Direct Deposit Extra Info: I purchased this from JohnA around 4 years ago who bought it from Steve M around 1 year prior to that. According to SteveM, it was Mick Malony’s personal unit. John purchased it with no volume remote, so had it sent back to Supratek to have one fitted. At the same time, it had a once over and got a clean bill of health. Here we have a DHT 300B Pre-Amp which also features 2 MC phono stages and remote volume control. Also has a separate power supply The back of the Grange is feature-packed. It is currently configured to have 5 RCA Inputs; 2 RCA Outputs; 1 Balanced Output; 2 switched phono Inputs (you can use two turntables and switch on the fly between them); cartridge loading switch; (loading options are 10ohm, 100ohm, 1000ohm 47k) 1 Tape Out; and it has a Negative Feedback settings switch. The feedback switch allows you to match the impedance response to any amplifier you might want to use, solid state or valve. Up top on the solid 2mm copper chassis and in front are controls for Channel Balance; Source Select and Volume; a Mute switch, a pair of unused tube sockets and a pair of obsolete switches which were used for tube loading when trying out different DHT tubes 300B was chosen as the best sounding on this Pre. The top is also plated in 18 Karat gold. It is a little stained as can be seen in the photos, but of course does not hinder the performance of the unit and still looks amazing. Photos have a tendency to exaggerate the effect. Tubes supplied will be 2 x 300B (Shuguang Treasure’s) 2 x 6sn7 2 x 6e6p 2 x 6922 2 x e180/6688 4 x 5881 1 x 5ar4 I also have some spares which will come with it I would prefer a local buyer, but am happy to ship at your expense, but only if I feel I can package it up safely and securely for transport. I will however take no responsibility if it is damaged during transport. The unit is reasonably heavy (both pieces), so needs some serious packing. There is plenty of info on the net, but here is something from our very own SteveM. http://stevem1960.blogspot.com/ If you have any further questions or want to arrange a time to have a listen, please let me know. Regards Andrew Pictures:
  7. Item: Supratek Dual 300B Cabernet Preamp Location: ACT Price: $3200 Item Condition: Very good Reason for selling: I bought it to use with my vinyl rig and it is very impressive only trouble is I also bought a Bel Canto Preamp DAC the same week it has inputs for everything including analogue and being a nice compact unit it has won the space competition. Payment Method: Pickup - Cash, Paypal, COD Only Extra Info: I may regret selling this unit and if no one contacts me then that's ok too I'll be happy to hold on to it. It includes 2 sets of spare main tubes and I have done a mini service on it which consisted of spraying the contacts with Servisol and tightening the tube holder pin clamps to ensure a nice strong contact. This is a serious Preamp top of the line in the Supratek range make no mistake it's the bees Knees. Postage is possible I have boxes but it's not a preferred option and I'll be happy to demo it to any potential buyer. Pictures:

  9. I read previously that changing the rectifier valve on the Supratek power supply unit can make significant changes in sound quality. In particular, a NOS Bendix 6106 will tighten up the bass. In my case, the standard rectifier and another I tried ( NOS Mullard EZ34) provided deep bass, but it was not as tight as I would like. Well the difference with the Bendix 6106 is profound, in that the bass is as tight as one could hope for ( as tight as a decent solid state setup - and I am using all valves). I have the Supratek Cabernet Dual, and even dialling up the separate bass feed ( I use 6H30's for bass and 101d's for mid-high frequencies through 4 monoblock power amps), the bass became more pronounced but still very tight. So before fiddling with power amps and speakers to optimise bass response, the culprit could well be the choice of rectifier valve in the Supratek preamp.
  10. Item: Supratek Cortese Preamplifier Location: Hobart Price:$3,000 Item Condition:Excellent Reason for selling:Now using digital volume control. Payment Method: Paypal, COD, or bank transfer Extra Info:Serial number #369 purchased in 2007. Please see the Supratek website for images and reviews … http://www.supratek.biz/cortese.php Price includes shipping by Australia Post. (Other shipping options by negotiation.) User manual is included in print and pdf file. This has been a great preamp for me. I mostly listen to classical and jazz and the Cortese is wonderful for recordings of large orchestras and opera and especially for the sweet sounding violins. The Cortese includes a very good phono stage but I have not used this in recent years. I have owned the unit from new and the preamp has not been modified except for replacing some tubes as follows … In late 2011 I replaced a faulty rectifier tube with a NOS National GZ34. In November 2012 after one channel became microphonic I replaced the two 6SN7 tubes with new Tung Sol 6SN7GTB matched pair. My experience was that the Tung Sol tubes improved the bass and high frequencies noticeably without losing any of the warmth and magic from the mid range. Caveats: One of the four line level inputs is swapped left-right. The remote control has gone missing in one of our recent house moves. The power supply is in a separate chassis and recommended to keep well separated from the preamp chassis to prevent any hum. (No problems here.) This is a great sounding valve preamplifier that is strongly engineered and looks beautiful.
