If this amp is to serve in a dual channel system in a reasonably sized room I'd heartily recommend a PP 2A3 amp.
With attention paid to PS design and driver stage you'd be amazed about the amount of power you can squeeze out of them.
There's something about those DHT triodes that just defies logic...
In the smallish studio I usually work from I have a simple two way speakersystem with a 2A3 PP and a Plextor CD-Rom, software controlled.
This stuff rocks, is detailed and throws a stereo image to make quite a few big boys envious.
Moreover, for a CD based system, this is actually one I can listen to for hours.
Spot the Ultranalog analogy and I'll consider you a smart person...

Transducer, I'd suspect the power supply electrolytics. Poke around the input and output rails with a meter and a scope to see if the B+ voltage is the required 390V and that the input is more or less 450V, with low ripple. FWIW, that's the only part I've lost on mine in about 10 years of service and some pretty terrifying modifications.
Make sure you observe appropriate safety precations when poking around high voltages like this. It's WAY too easy to brush up against something you shouldn't, and we don't have so many members at diyAudio that we can afford to lose any.
