Extra heatsinks for the "regulators"?
Hi eveyone,
thankyou for your comments.
Those vertical fin heatsinks are are for the Power J fet and are insulated from the chassic on nylon spaces and nylon bolts (per the article). They are rated at 1.1 c per watt so with the Power fet disspating 4- 6 watts will operate at 29 c temp in a room ambient temperature of 25C.

ps I hope to post more images soon.

And stuffed the pcbs.
You will note I have used some Auricaps for the authorised audio bypass capacitors. The main capacitor is rated 80volt.
Most of the parts are standard meta film 1/4 watt, some Dale 1/4 I had on hand and some Panasonic FC in selected postion.
The main pcb will run flying leads to the IRFP240's on the heatsinks with gate stopper resisters soldered directly to the pins.
I will try and make an effort to get it fully assembled by next weekend.
On Friday I have an RDO so that will be a Diy Passlabs public holiday!
