has anyone bought these resistors or know of a supplier .

Cheers .[/b]

Hello 56,

I hope all is well for you- unfortunately we didn't catch up last week- maybe next time. There are bulk metal foil resistors available from RS components. They look like a small piece of choclate I suppose. Mohan uses the 25W ones I believe.

All RS components resistors:

All Their Vishay:

Hello JA

I didn't go to Mohan's had dayshift on the Friday with a 0630 start .

The Vishay naked S102's were made for NASA there not incapsulated there is a S102 similar to the Caddocks.

Are Mohans similar to these which are Caddocks MK132 & MR930

Hello 56,

No Mohan's are a flat block about 10mm x 20mm and about 4mm thick. They are also designed with a flat partial aluminium base for heat transfer. RS has plenty of caddock stuff though. I couldn't find the s102 vishay- although I saw others.

Thanks JA

They look like surface mount resistors normally found on PCB's.

I use the Caddock MK132 & MR930,s I find them neutral very good in digital ciruits and pre-amps.

I want to use the Naked S102 in the IV position in the dac.

Hello 56,

That sounds like an interesting mod. Will you be using any buffer opamp (or tube) on the output after the IV?

it uses a valve buffer 6C45pi in Mundorf silver/oil caps.

cheers.

I changed the GE 5v4 rec's to brimars 5v4 rec's and took the sound to another class.

Hi 56,looks like some nice handywork of yours there. ;)

Not that I really know what I'm looking at :)

Joz it's 15kg's of DAC .

JA I think you have heard the standard version at Mohan's it was built by Scott Thomson .

All the left side & half way up the right is power supply designed buy BlackArt Audio

This what it looked like orignally but I already changed caps & resistors.

I have 1 more Dac to modify with power supply upgrade ,I was looking at changing to output trannys instead of caps.

cheers.
