suds
can you please educate us on the heat sinks and transformers required
exactly what would be needed here

i might have a direct source for heat sinks ( the guys who actaully own the extrusion plant )
i want to see if any of their heat sinks would do

ditto on the transofrmers too

Sure.. I am checking on sources for Heatsink and Transformer, will pot about it soon...

I got few heat Sink dealers, have to check if that have Heat sink specific to First Watt Amplifiers.. will check and post here.

Also.. I will be getting F3 and F1 Parts soon.. already ordered..
I got a dealer who will be sourcing LU1014.

F1 and F3 Kits will be available with Parts and PCB.

suds you misunderstood

i meant please do educate us on exactly what heat sink and transformers we should look for

it so happens i have a heat sink source myself
One owns an AL extrusion firm and one makes heatsinks for various electronic majors

 

[suds]

Heat Sink Requirements are there in relevant Service Manuals.

For Pass F5 Amp
Idle heat dissipation would be around 62 watts (At 1.3 amps per channel)
heat sink rated at about .6 deg C./watt for each transistor.
Finned aluminum, with a series of 2 fins attached to an 8 by 6 base, with mounting surface of 1/4inch device need to be firmly attached to the heat sink. The mounting surface use silicone pads / Mica and silicone grease are the best.

Below are link to heat sink images:
