Vinnie, from the sketchy info (sorry if you've provided info I haven't seen) I can only deduce that you are comparing apples with oranges. No doubt the circuits are completely different. The power supply, the driver and the output trannies, not to mention the other parts and tubes, are all critical. The only way you can really compare is to build an amp that can easily cater for both tubes and even then it won't be a perfect comparison. Alternatively you need to build ideal amps (as much as possible) using very similar circuits and parts. Actually you'd be surprised just how similar amps sound when you just change the OP tubes and nothing else. Obviously you need to change the OP TX tapping and you'd be tying the 845's hands behind its back power wise.Don't give up on 845s so easily, I've built everything from 45s up and I still prefer my SE 845s. Granted I need the power on my main speakers (ESL/line array combo) but I've tried many others apart from horns. Take TKs advice and post some more info, particularly a schematic of both amps if possible before you dismantle the 845s, maybe it’s something obvious.
