Big OTL I built some time ago.
In with his Lamm preamp, had to replace all the five toggle switches on the front of the Lamm with quality ones as seen in Ecofan Boost-its, but used the flat toggle ones.
OTL needed a couple of new silicon diodes.

Are those 6080 output valves? What output power do you get from that?

I love Hendrix for so many reasons. He was so much more than just a blues guitarist - he played damn well any kind of guitar he wanted. In fact I'm not sure if he even played the guitar - he played music. - Stevie Ray Vaughan

Yes that's about the power of the big one as with that many 6080s there would be too much heat if too much HT voltage used. Would have been better as monoblocks.
Those monoblocks with four a side therefore give about 20WRMS each with somewhat more HT.
I like them better, and may even do more of them.
I found with the OTLs that even though they do like, 5HZ to 100KHZ they sounded bass heavy unless wired with 1mm silver wire. Then the tops keep up with the bass to listen to although on instruments just the same. So all those beasts are wired in the silver.
6080s get really hot with their 2.5amp heaters and high current low voltage HT.

Try this link again Adam.

Just checked it, still works.
Maybe they are miffed with me for standing up to the bullshit!
Here's a link to the second page:

Otherwise it's under "Pics and Looks": "Jack Track".

OTL 001.jpgAdam was prevented from accessing this thread of mine on the Skirtcafe, so I have taken these screen shots which should enable the drift to be got. Me under attack!
