Any rumor or spy photos of T2? :evil:
Quick question about the enclosure of the amp and heat dissipation, I was thinking of using a wood veneer to cover the top and sides of the enclosure with apertures for vents but obviously am mindful that this will prevent heat generated from being transferred so effectively through the case for cooling. Might heat sinks mounted on the underside of the base help offset this cosmetic approach or am I being unduly cautious about the amount of heat the amp dissipates through its enclosure and leaving the base and ends as normal might still be sufficient?
Thanks it doesn't look such a good option if the amp diffuses significant heat through the case work.
The Torpedo is temporarily out of stock. I've had some transformer issues with Edcor and I've gotten hit in-between enclosure manufacturing runs. New cases should arrive within a day or two, but I have to have them anodized and laser-etched locally. That may take another 2-3 weeks. Rest assured, I will get the Torpedo back in stock as quickly as possible.

At least that means they must be selling!
Yes, that's exactly right.There's quite a demand for the Torpedo, now.
Good news, though - Edcor is currently working on a new set of transformers. Plus, a new shipment of cases arrived on my doorstep yesterday. I'll wash them all this weekend and take them to the anodizer on Monday. They'll probably keep them a week and then off to the laser-etcher for another week. If we're lucky, this will all coincide with receiving Edcor's replacements.
Meanwhile, Dsavitsk sent me quite a few new Torpedo designs that I'm currently playing with. We've always had the Torpedo II, but it used a prohibitively expensive toroid to remove the noise. That was all before the rectifier changes/snubber caps, though. Now I have a Torpedo II with a standard Edcor PT and I'm applying the tweaks. If it works out, we may be ordering PCB's right away.
Then there's the Torpedo III ...
Lots of exciting stuff happening!
Quick question...what are the ratings on the power transformer for both the B+ and heaters?
200V at 40ma and 8.5V at 1.5A.
as an aside: if you guys aren't too far into prototyping: have a serious look at the lm2596 for heaters. A switcher reg gives quite a few advantages: you get less losses and thus less heat and you can use a higher voltage/lower current secondary (easier on the transformer).
And be sure to try the 6E5P. It's a great tube for this particular application.
For now, the T2 has a totally different topology.
