After almost 3 months of having a amplifier project in the way on my coffee table in my living room I finally got enough ambition to finish the Poddwatt Amp: DIY 5751 SRPP / EL84 (6BQ5) Push-Pull Tube Amp. It shows about 25 volts too high on the B+ and so far I haven`t put any input into it yet. Have to go to work now so I`ll do all that tomorrow. I`ll try to post some pictures of it now.

Looking good. Nice use of the SMPS which is an economical way to heat the tubes.

Thanks Gio, I have listened to the amp for 2 hours now and it is just great. No noises or surprises. Really has great sound into a pair of Polk Audio TSi100 bookshelf speakers (4 ohms). I need to put some silicone sealant on the exposed OP tranny terminals as they are really touchable. ZAPPPP! I like how easy it is now to post pictures on the site. Robert Parsh

Yes, you want to cover the tabs up well. :hot: Heat-shrink (check voltage rating), insulated blade disconnects or transformer covers are options too.
Cheers
