I don't have anything to add to the actual discussion, but just wanted to chip in that the PCL86 tube to my understanding (based on some online reading, FWIW) is pretty similar to the ECL86, only it uses 12V heaters... So that could be an option if you could fit a separate transformer for heaters at...

Yeah, realised my wires crossed there, sorry about that.

Yeah. I can't really help you with your pending addiction or with finding a power transformer. There must be a source in Australia or SE Asia for a 240V primary with 62.5-62.5 high voltage secondary and 6.3V filament windings. I don't think I'd go below 125V but anything above that will probably gi...

So, quick update about the Tall Bird; Had some time to get my test setup sorted, and found that the 12au7 triodes are driving the reverb tank itself, and the first one just after the input. So it goes input 12au7, split into > dwell 12ax7 > 12au7 driver > reverb tank > 12ax7 recovery > dry 12ax7 > m...

The power transformer that I'm using might be putting out too high voltages for the amp, but that doesn't seem to affect the Vinny part... Could that be enough reason for the oscillations? I've tested with another (similar) reverb tank, and neither gets signal. Hi Bodhi and everyone, I'm new to amp...

Hi everyone, thanks for the amazing resource and doing a lot of work to get these builds working! :D I'm fairly new at amp building and working on a Dizzy Bird. I've had the Vinny part working well as far as I can tell for about a a week now, but the tall bird reverb section is giving me problems.....
