Hi palstanturhin,

Great looking amps. Please can you tell me how they are assembled. I assume the amp in the first pic has threaded inserts in the wood to allow the front panel the be attatched, but how is the second one assembled?

Palstanturhin,

Any internal shots?

portreathbeach got it right with the first set. The wood used in these is oak, very hard, easily threaded...Second amp has an alu frame made of different alu-profiles, like L,I,C, and even O!The heatsinks are first attached to similar length L-profiles. L-profiles also on the front and back... To these are attached the front and back plates 60mm wide 4mm thick alu... and the wooden sides.Bottom plate is 1mm alu sheet, and fastened with small L-profiles again to the 'main frame'...Back plate stays on with the binding posts and what ever connectors, front plate with the potentiometer and the toggle switch.Size is: W20cm(8"), H6cm(2.4"), D25cm(10")...No shots inside unfortunately...

Sound clean and soft, maybe not so powerful like PA100 and PA150 but more detailed.

Professor,

Very, very nice construction. I was attracted to your use of one transformer for multiple voltages. I am working on a build that requires four -Amp x 2, DAC, Pre and Lighter Note. I may use discrete transformers for the amps but would still like to combine the rest on one toroid if possible.

Can you point me to a source where I can get the information I need? I'm assuming you did a DIY board of some type.

Also, what's the flavor of the white wire?

Thanks

I buy 2x25V toroid and wind missing windings myself. Originally I reel up some turns and I define how many it is necessary turns on one volt. Further I multiply the received number of turns on necessary voltage. For examlpe, you have received 5 turns on 1 volt, you need 25 volts, then you need 5*25=125 turns.
White wire is copper covered with silver in teflon.

Professor - Now that's what I call DIY - Impressive!

If you don't mind, what is the green board under the transformer?
