I guess now Small Bear sells kits for NPN or PNP transistors for Rangemasters, Fuzz Faces and Tone Benders. They're not as expensive as paying to have them select individual transistors for the gain/leakage you want but they're not far off. Add shipping to the UK and you've got a pretty...

You can look at Small Bear Electronics to get an idea of what they charge for pre-sorted and tested PNP and NPN transistors and that might translate to what you'd pay in the UK after factoring in the exchange rate. I'd look for 2N1306 or eve 2N1304s or their military equivalents too, because...

FWIW, I used a CV7351 that was about 95-100 hFE and it sounds like the real Thorpy Have Blue pedal I have sitting next to it - and coincidentally, using RG Keen's method of measuring the transistor in the Thorpy pedal, I get ~90 hFE with ~.098 mA for the leakage. I get ~85 hFE with ~.115 mA for...

Is there a schematic available for the new Fuzzy Fox design? Got the old build doc but it doesn't seem to quite align with the new board.

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...

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. Here's the ratings of the switch frequently used in Marshall clones...

I'm glad you got it resolved! Re: Re: Mercury Magnetics: Dave Hill is the guy you usually talk to when you call or shoot them an email and he's super helpful with specs. For more future reference, for those that have access to a Windows PC there's this tool: Duncan PSUD2. This will let you...

Remington Wire is what I've used for the past 7-8 years. If you want pre-tinned you need to look at their Topcoat selection: Topcoat Wire They offer kits of UL1007 and UL1015 in 24 and 22 AWG of 10 or 6 colors in 25 ft or 100 ft spools. It's no different than the Weico wire you'd get from...

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...

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...

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...
