Extra Info:
 I purchased this in September 2010, I think I am the 3^rd owner. It has seen little use in my system due to having a keeper integrated, but I liked it so much I wanted to keep it for future use, and would get it out every now and then for a spin. It has also sat in a few other SNA member’s systems as a temporary loaner. Now I’m going DSP active so I will never get to use it. I think the unit is probably about 10 years old.

 

The only mod I am aware of is the previous owner swapped out the Rel caps for Dynamic, I will include the Rel’s with the sale if you would like to return the unit to stock.  I had Trevor at Rage Audio service the amp a few weeks ago so you can buy with confidence. He serviced and cleaned the expensive Elma 24 so it's as good as new.

 

One small mark on the top case in the corner (see pic), and a slightly squashed tube cooler (see pic).

 

Sale includes 4 sets of 12AU7 tubes. NOS Phillips Miniwatt, Phillips Jan 5814A, Electro Harmonix, and Gold Lion ECC82/B749, so a bit tube rolling to get you started. I have the manual somewhere as well, but it isn't really informative.

 

I would prefer local pick-up but if there are no takers I’ll open the sale to interstate buyers. You are welcome to test the amp in my system with your power amp, or one of mine.

 

Plenty of info online for this, Greg Osborn currently retails them for $2895. Lowballer's ignored. It's a great deal for a fully serviced pre-amp with 4 sets of tubes, hence $750 Firm,

 

I found the presentation very detailed with no tubey honey at all. It has a really fine top-end, and a firm grip on the bass.

Ignore dates on the pics, I took them today 1st January 2016.

I have some interstate interest on this, but would still prefer to sell locally. If you are local and interested let me know, otherwise it will be heading west (where it originally came from). They seem to be hoarding audio gear over there.
