I'm hearing Pa is moving his entire production here ; main reason is Amperage bill , same as fact that here ppl can have properly strong amps , directly mains powered ;

and audiograde fuses are weaker , so cheaper

(not mentioning fact that I can listen da muzak , and drying my hear , in same time )

6L6, I look forward to your write-up on your F5T build. Your write-ups are outstanding with excellent photos. I have your previous writeup on the O2 bookmarked.

Is there any post that talk about heat dissipation, as far as what is needed for heat sinks. I ask as I am interested in maybe sourcing some heat sinks.

Thanks

After I thought about that for a min. A heat sink thats 6"x6" with 1" tall fins would be about right.

on heatsinks... I think that ones from the store chassis have a bit to thin base. With not enough thickness of the base you can have a big temp. gradient(hot near transistor and cool further). Thats what I have with my F5T. I ordered 3/8"x6"12" aluminum bars and will use them to increase base thickness of my sinks. I will let you know if it helps.
