Title: Champ Ultra build Post by: L_Z_nut on September 04, 2009, 12:33:44 AM Big hello to the forum first off.
Just finished this up last night, I ordered an unassembled board kit. Sounds fantastic through my stock valve junior cab. I'm still trying to decide whether or not I want to make it a mini 1x12 stack (like my valve junior) or make it a combo.

I've only modded my valve junior before. I made some mistakes, the worst of which was using the 470ohm resistor (right of the filter caps) in the 47ohm's spot. The leads were too short to put it through the eyelets so i had to improvise. The chassis was given to me by my stepfather. I was told it's very high quality aluminum, and I believe it cause it's very stiff/solid for aluminum. I could of also made the wiring a little cleaner, especially the heater wires to the 12AX7's. I had no idea how hard it was to do the heaters for those tubes, but I found a pretty good instructional vid on youtube. She's still very quiet considering the sloppy heater wires though, and this was a very fun experience for me, especially because she fired up on the first try with no problems whatsoever. :chairdance: Nik was super helpful and sent my package extremely fast. Thanks again Nik!! Enjoy the pics! Title: Re: Champ Ultra build Post by: tfarny on September 05, 2009, 09:32:34 PM Looks great, congrats on doing it yourself. My ultra champ is on the way, but I ordered the completed chassis. Not quite ready to assemble from scratch yet.

Nik sure does supply a nice product. Not much to complain about really. For some reason, I don't care much for the Alpha pots. I have never had a problem with them, so my suspicion is unfounded at this point. The guts look pretty much like a CTS to me. Anyway...... My vote would be for a half stack (mini). I built the BFVC in a head. I am not joking when I say it is one of my favorite amps, and we have all kinds of amps. There are power limitations of course, but all amps have that in one form or another. So I cast another vote for a head, and another vote.......... Good Luck Title: Re: Champ Ultra build Post by: L_Z_nut on September 06, 2009, 05:30:07 PM Thanks!!
Yeah a mini stack it will be. They just look cooler! ;D I've been using alpha's for years in pedals, and I've never had a problem... except for the values not being exactly what they say they are, but I've used CTS that were off as well so... I'll be building the cabinets myself as well, they'll be stained and not tolexed. Thanks again!! I'll post the cabs as soon as I can get them done... which might not be for a little while. :( |
