Well, since there are no responses, let me see if I can answer some things for you.
Speaking from experience, I've owned my 'canes for the last 3 mos. or so. They are the latest version which has an improved chassis, a triode switch, the green square can PIO caps, and improved bias circuitry.
Looking inside the amps, I found a hodge podge of wires, as everything is point to point wired, besides the bias PC board. But alas, the wiring is neat, and the solder joints were decent for the most part.
I know that DT checks each amp for proper operation, tubes, etc. prior to shipping out. The tubes came labeled with respective socket numbers. I replaced the stock input tubes with EH 6sn7s, and there was a whole lot of hum and noise, but after putting the orig. tubes back, the hum and noise was gone. After a while, I rearranged the EH tubes into varying sockets until I found that the combination with the least amount of noise and hum. There was quite a bit of hum coming from one of the amps, which I fixed with a cheater plug. Perhaps a ground loop in my wiring somehwere??
I've had a couple of tubes go out on me, and a bias resistor on one of the tubes on one amp blew as well, and DT was quick to replace the tubes and sent me various parts to fix the bias problem myself (which I had no problem doing, as I'm techie enough to do it). They gave me other options to fix the amp, since the amp is under warranty: take it to a local technician, for which they would reimburse me, or to send the amp back to them (to Canada, too $$$). I am more than pleased with the service that I've gotten from them in helping me troubleshoot my initial problems and sending me the appropriate parts.
I like the amps very much because:
1) first and foremost, they sound wonderful
2) they are a simple design, therefore easy for me to troubleshoot and maintain.
3) they look cool and
4) did I say they sound great....
Hope this you....
