KSA 100 from Jim's Audio on EBAY

crazycloud · 20th February 2011, 05:03 PM

I bought 2 of these boards today from Ebay

High Power Pure Class A amplifier PCB KSA100 ! - eBay (item 320659739390 end time Mar-21-11 10:04:10 PDT)

Can anyone tell me about the finished product?
Does anyone have experience building this?

Has anyone bought toroid transformers to build a supply for it?

I should receive the boards in 3 weeks.
thanks

I have ordered the same boards myself. They are good quality if you ask me.

I am far from finished, but the most resistors are already soldred to the PCB.

Have you received the PCB's already?

I have a power supply right from a real KSA-300 for sale... It does not have a transformer, just caps, rectifier, etc...

I also have the Chassis from a real KSA-300 that I don't know if I want to sell...but if price is right....

Nice! I would be really interested if I lived in America, but I live in Holland instead, so I think shipping would be too expensive for me.

Excelent boards. Just be careful. There's a misprint on the boards. Look at the schematic. Resistors 20k and 47k next to the 150R should be 4k7 on the right front side of the boards

How stupid of me, didn't notice the misprint. Thanks for your input Neychi :-)

Do you have this boards as well?
