I will start a small group buy for
a) FC-100 Amp Boards
b) Stackable active rectifiier LT3062 front end PSU
c) Active rectifier for screw contact caps (e.g. 22000µF/63V RM22.2)
All boards with 2oz copper.
a) and c) 2mm thickness. b) 1.6mm thickness.
Green soldermask and white silkscreen.
The boards never tested in reality but the FC-100 is a bullet proof design.
The FC-100 is based on Roender´s design.
https://www.diyaudio.com/community/threads/rmi-fc100-a-single-stage-audio-power-amplifier.111756/
These PCB design is based on Rudi’s design with some little improvements.
All Pads are bigger for better soldering. The traces are bigger.
More space for the dc coupling cap at the input (I will use a clarity esa).
A small bridge for feedback instead a long wire (J1)
If someone is interested, I can provide all layers as pdf to double ckeck them with the schematics.
I will order to the end of next week (26.09.2021).
The group buy is only made when a minimum amount of 10 boards is reached and payed.
The next possible qty is 20 of each pcb. In this case I will donate the carry-over to diyaudio.
Shipping price is for one pcb set.
DHL EU shipping by registered mail is 8,89€.
Outside EU 14,89€ with delivery time >30 days (otherwise 3-5 days UPS for around 46,99€)
Please answer here with your reqirement as follow
FC-100: qty
FE PSU: qty
Screw Cap Rectifier: qty
and send me also a PN with the same information and your delivery address.
I add only paid pcb´s to the order list.
Thanks!

You could buy the parts from user ztr.
DacGear
Some parts are hard to get.
I only can offer matched onsemi BC550C/BC560C.
The ebay Toshibas often fakes.
You could buy Sanyo here

Thanks again - what value of capacitor are you looking at?
Now I see you mention 22,000uF 63VDC in the 1st post.
I use 4x 22.000uF/63V for my power amp.
