Just heard back from techs. I brought them the set of TAD EL34B STRs. I had neglected to tell them that the 20-year-old Groove Tubes I'd had in the amp were starting to burn orange/red, figuring they would just bias the new set of tubes. They are suggesting that, based on the TAD set I brought them,...

Thank you, gents! Just got my matched quad of TADs; will see what the folks at Triple S say about the bias voltage.

Happy New Year all! I have to take my '72 DR-103 in for rebiasing (tubes began glowing red; hasn't had new tubes or bias since purchased around 20 years ago). I had another DR-103 in and had bought a current production set of Mullard repros. According to the tech notes on the receipt, the tubes were...

I've been dying to try daisy chaining a couple of Hiwatt heads, or a Hiwatt and a Marshall head, and wondered the best way to do it (which inputs to use). Also, by extension, I imagine I would be able to daisy chain my SA212 and my Hi-Tone SA212, correct? Thanks!

Very happy to have recently acquired a rare 200-watt PA, DR 203 No. 3708. Has two minor, well-detailed mods, one to the bias adjustments to hone them a bit more, and one to the speaker outputs to allow single-cabinet operation. Cranked it through my two 412s and didn't feel particularly overwhelmed ...

You can see it at 3:15 and 3:22 as well!! How could he not choose an HT rig? Well, when they come back to MSG he can borrow one of mine : )

Hello all. Really glad to be part of this group. Hiwatts have been a love of mine since I first laid eyes on a clip of Pete T "playing" his amp by whacking up all the knobs, then seeing "The Kids are Alright" doc on HBO or some such. (Or maybe it was on a show called Night Flight...
