99% done, just need to finish a bit on the chassis wood.
It sounds fantastic!

Hi, Classic style serious with a touch of blue aspect that match with any other device, definitively my style. Let me make a question, the output valves are 6NJ6 or 6JN6 ? Can you show the electronic diagram of it?

Deviating a bit from my original intent, of keeping things in chronological order- here's a set of amps and preamp which I built, that I just sold this morning.

Click the image to open in full size.

The amps started as a very rusted set of Dynaco MK III chassis, that I got in pieces. In fact, here's how bad they were to start with:

Since I didn't get any transformers, I decided to experiment a bit. I have always been a big fan of 6L6 type tubes- so, I converted the design over to 6L6GCs. The output transformers are 6.6K 60 watt UL interleaved-winding Hammond units, and the power transformers were from a pair of Thomas organ amps. The feedback loop and bias circuits were re-worked to work correctly with the new tubes and transformers, and the power supply was converted to solid-state rectification, with much more capacitance than stock. Output is about 40w/ch, with 4 and 8 ohm outputs.

Click the image to open in full size.

The preamp was built from scratch, to be a close cosmetic match to the amp chassis. The phono stage is a modified Dynaco PAS type (using a bit of each of the Latino and Curcio mods, melded), and the line stage is a single-gain-stage buffered circuit, that I have worked up myself. It's completely point-to-point wired inside (no circuit boards), with a solid-state rectified power supply with DC heaters.

It was a little sad to see these go, as they sounded SO GOOD (especially the mids- and they were SO dynamic). But, now I have resources to buy parts to build more amps!

Regards,
Gordon.
