Re: 2018 Carverfest Tube Power Amplifier Build

Happy days - It seems that finally the two boards I lack (for those two amp kits I'm trying to deliver) are on the way. Now that the Rocky Mountain audio get-together is over, Jordon is back at work, and saying he will not only send them, but they will be finished/populated. Hope that includes the t...

Re: Carverfest Tube Amp Technical Discussion

It's Official - the first ECO. When I talked to Bob today he was working in his lab. He wanted me to post his solution to the bias adjustment problem, and now I see it's already been mentioned here. It involves changes to two resistor values on the main board, near the wires that lead from the bias ...

Re: 2018 Carverfest Tube Power Amplifier Build

Finally got home from NC, and just finished unpacking late this morning. I have two amp kits, for two different paid-for buyers in the area. But on inspection, each kit lacks something. I expected there to be no input or output terminals, and in that I was not disappointed, but those will follow lat...

Re: 2018 Carverfest Tube Power Amplifier Build

The Amp boards arrived Friday afternoon, along with their parts, all except the tube sockets, which can easily be added later. 75 boards, and some 6090 parts - resistors, caps, and diodes. Going insane sorting them all out and labeling them as ti R13, C7, etc. Extremely glad I didn't post any schema...

Dennis47 - Haven't seen anything of Bob (or anybody else) yet today, but when I do, I'll ask him.

Re: 2018 Carverfest Tube Power Amplifier Build

Bob brought a few tubes with him - KT120s are Tung-Sol, and the 12AT7s and 12AX7s are JJs.

Re: 2018 Carverfest Tube Power Amplifier Build

"Bob's probably making final tweaks by changing various cap/resistor values looking for improvements. If boards are made then the circuit won't change without being modded with point-2-point wire now. Hope everything makes it to CF on schedule." Yeah, Bob can't ever say 'it's perfect'. But it's jus...

Re: 2018 Carverfest Tube Power Amplifier Build

No schematic yet - Jordon says Bob keeps changing things, so not worth printing. Probably won't have any far enough ahead to order anything.

Re: 2018 Carverfest Tube Power Amplifier Build

Actually, I asked specifically about hole size, and Jordon said nothing large needed - just little drillbits for small screws, etc.

Re: 2018 Carverfest Tube Power Amplifier Build

News from Bob's GM, Jordon: It looks like a close call for receiving the kit materials on time. The shipment might not get to the mountain until maybe that first Saturday. That was the original day chosen to hand out the kits, and the good news (for me, at least) is that the assembly manual will be ...

Re: 2018 Carverfest Tube Power Amplifier Build

Talked with Bob again just a few minutes ago, and he now tells me that the amps will have two circuit boards - one for both stereo channels and the other for the power supplies. A couple of amplifiers are already built and working, and as usual he can't say enough about how good they sound... Earlie...
