    Guitar Amp Power Transformer 120/220V switch question

    AES sells this Carling switch and it will work fine for what you want to do with it: https://www.tubesandmore.com/products/switch-carling-toggle-dpdt-solder-lugs-0 You could use the rotary and just wire up two of the switches, but that would also be overkill and you'd need to cut a 1-3/16" hole...

    Guitar Amp Power Transformer 120/220V switch question

    If you go by the usual choice for changing primary voltages, yes it's rated for amperage almost triple what the amp is capable of pulling before the mains fuse blows, but there's really no downside to using that switch either.

    SOLVED! Lowering B+ on a 5F11 Vibrolux clone (fixed bias woes)

    I think this is my fault. Your PT is perfectly fine. I really should have mentioned specifically where to install that kit. You can only install the kit off the center tap reliably if you're dealing with a cathode biased power section which will not have this issue, otherwise you can easily run...

    SOLVED! Lowering B+ on a 5F11 Vibrolux clone (fixed bias woes)

    Hi, long time lurker here and not very active as a poster but I might be able to help. I've been designing and building amps for a long time now, so I've had a lot of experience with modern power transformers. Your issue is going to be the much lower coil resistance in the newer transformers vs...

    Kliche Mini w/ 3PDT Buffered Bypass Switch Breakout Board

    Apologies if this has been asked before, but I couldn't find it by searching. I have a few of the 3PDT Buffered Bypass Switch breakout boards around and was thinking about retro-fitting a Kliche Mini with this switchable breakout board, but are they even compatible? I've done this with a few...
