Man, that Plexi case is nice! Especially the matching knob, I think it ties everything together very nicely! It probably looks even better in person too! Nice job!

Tedro, those look great. Very well done!

Here's a CMoy I just finished up. I bought the board from Zigis and put it in a Hammond Case. Sounds great!

Extremely sweet case work, Tedro! I was never good at case work...

Default AMB Beta18 / Recycled Dynaco Completed.

I just completed the Ti Kan SDS upgraded amp. Installed in a salvaged Dynaco PAT4 preamp. All boards hard wired on RS perf boards. Matched output pairs ordered from AMB and most others from the usual... Digikey and Mouser. Alps Black beauty (100K) up front with a BB opa2134 socketed. I plan on trying the AD8066 opamp in the future. I'm running 80 mA. bias with +-15V. The LM317 and LM337 run on RS heatsinks. I was concerned, at first about the regulator temps., but the heatsinks measure just under 50 deg. C. Seems to be a safe margin.
All I can say is that it is extremely clean and dead Quiet! I know this design is a bit dated, but it is quite capable and fit quite well into the old Dynaco chassis. Still need to figure out how to create some venting on the top cover.

Very nice on the SDS! Did you do that all from the schematic?

Yes.......... all hard wired from the schematics. I wanted to seperate the supply sections from the audio board as far as possible. Supply noise is not an issue here.
