    Go to this website. I recall a thread there probably from 8-10 years ago in the bass section about recharging those. Might be some info in the pickup section too.

    Another thing to keep in mind is that if you have a 350V power transformer like you suggested above, with a solid state bridge rectifier that will be 490V with no load. When you put a load on it then...

    Yeah I started with that too, but then gutted it to start over. Ideally I would have moved the transformers away from each other a bit. They are both "Z" mounted, and since they are so close I...

    I gutted mine and started over with my own circuit. The transformers are too close together with the same orientation on the stock chassis, so if you turn the gain up then it will hum more than it...

    I did a whole bunch of modding and work to a CHB 100. I have a second one here to duplicate what I did on the first one. They're pretty cool amps, though the chassis layout is poor, especially where...

    I would just duplicate the parts that they used if you want that sound. A large part of the sound of those amps is the unbalanced paraphase inverter, but even something as simple as using ceramic...

    I had what I thought was ghost notes due to oscillation or bad filter caps, or undersized filter caps on my 1993 Korg AC30 since new, and it was actually cone cry from the Celestion Blue speakers....

    I believe that GEC invented the kinkless tetrodes to get around a Phillips patent on the pentode design, but they initially had trouble with it, so since they were affiliated with RCA in the uSA,...

    There is no such thing as a 'beam pentode' even though many manuals termed it as such. It is a beam tetrode since one of the 5 elements of the pentode is replaced with beam forming plates, thus...

    The 6973 was derived from the 6V6GT according to Vacuum Tube Valley # 15. It is certainly a beam tetrode and not a pentode. It has a higher plate voltage capability than the 6CM6 and the gm is a...

    In one instance I had to replace a PT from a Magnatone 260 for a friend. That amp and a real 1951 Tele were his sound, so he needed it as close to original as it...

    As a side note, an interesting thing about the Beatles and Vox tones is that so many people assume they used AC30's for most of their stuff when the reality is quite different.
