6L6:
The chassis is a HiFi2000 Galaxy Magiorato, which the diyaudio store is now selling. I designed the front and rear panels and had Front Panel Express do all the hard work. The amp is LM3886-based and was sourced from chipamp.com, and was a project my younger daughter Jamie (now almost 18) and I worked on together 3 or 4 years ago. "JADE" is an acronym for "Jamie and Dad Experiment".
Incidentally, I just realized I posted photos of a non-Pass design on the Pass forum. Absolutely no insult was intended.

Scott
F5 Build
The heatsinks came from an old power plant, at 5 pounds each they are way oversized. The power transformer weighs in at seven pounds and was purchased on the surplus market years ago. I have included a capacitance multiplier circuit for the supply rails as I needed to drop about 5 volts to bring the supply voltage to 24 volts. A speaker protection circuit was included. I have built four of these monoblocks and am using the in a triamped system. I all the thirty years of building stereo equipment I must say this is by far the best sounding system I have yet to build. Thanks Nelson for all you contribute.

Clarkstuff, nice looking amp. what are those to-3 covers called and where can they be purchased? Thx Vince
The DCB1 is ready 🙂 More or less. Need stands and maybe some holes not to get too hot inside. 2 switch is in/output selector.
Thanks to Salas for the reg and ofc. Pass for the B1

The T03 covers came off an old amp. I do not know of a source. The chassis started as a single triode amplifier. Needless to say it did not work out. I prototyped the F5 on a whim and was impressed with the sound. The chassis was a natural for a F5 build. The capacitance multiplier removes all the ripple ( at least what I see on my scope ) even under load.
Farnell sell these and one is marked as US stock.

Wow ! Thanks for sharing, I will be using this in my next to build preamp for volume control 😀
Where did you buy these excellent looking knobs ?

Thank you. I attached the LED using hot glue. I roughed up the surface around it with some sandpaper to help it stick better.
