This is a good one. I've had it for years and taken many stabs at restoration. I finally made some progress. The amps, preamp, and tuner are now functionally. I also added some bluetooth. The record changer is going to be swapped and the RTR need serious help. The belts fell out the motor needs some work. All that being said I have a tuner and bluetooth for now.

 

The guts all spread out so we can find issues more easily.

That's a very nice amp with a great sound.

Thank you. I am very happy with it. So much so that I just ordered a "new" Dynaco Pas-M preamp from Kenny Russell over at getdynaco.com.

Is it from one of Dewares auctions?

No. This was Steve's. This is the father to every ufo25 amp out there. This is seen in every development post photo when he was designing posting results publicly before the final version released to all. Serial number #000. Steve ate and slept with this one for a while. It's a great piece.

You have a nice amp. Here's mine. Ordered April 2016. Received July 2016. Back then 4 month wait 😂

A few photos of a tube amp project completed recently.  Two channels, about 20WRMS/ch into 8Ohms.  Based somewhat on the Scott 299C output stage but using a solid-state, HV power supply design capable of substantially more power than is required for the push-pull 7591 pairs.    

 

Chassis CAD files were sent out for quote, the supplier (New England based) responded with pricing for larger quantities than I was considering.  Placed an order for a small lot of chassis assemblies.  All metal chassis assemblies are best for RFI/EMI/noise immunity.  The chassis assembly is the high-cost item in the build. Uses oversized Hammond or Lundahl output transformers.  Still waiting on a few finishing touches (knobs, graphics).  Was considering silk screening the top plate but perhaps some other time.

Snake Eyes.  Scott 299A, 22 years post NOSValves restoration.  Other than biasing occasionally, nothing has been done to it.  Did some "tube rolling" once to see if I was an "audiophile"...couldn't tell a difference so still just a guy that likes music.  Feeding Forte IIs.  Nothing to compare it to, it's all I've used since around 2002-2003.

I'm waiting on the same piece from Craig at NOSVALVES.  Looking forward to it. Had a 222c, from NOSVALVES and kick myself for getting rid of it, hence the purchase of the 299 from him.

All hooked up. Decware Zen amp, ChorusII speakers, and the very first Hsu research, Vtf-3 (front firing version) Absolutely gorgeous sounding~
