Really nice job! It's a really good circuit. The one thing which spoilt it for me a bit was C5. It makes the sound a bit fuzzier than my actual Marshalls. I would definitely recommend experimenting with smaller values there. In the end I put a bass pot in mine which goes from 220nF to 22µF...

Uncle Doug's is probably the best Tolexing video I have seen. Tolexing cabs gets easier with practise! And using actual Tolex makes the job easier too. A lot of vinyls designed for upholstery are too thick and makes covering a cab much harder than it needs to be. I also prefer to use the smelly...

They might resurrect it for you if you ask nicely!

Do Mercury Magnetics make anything suitable?

They'll have simply used one of the quite rare germanium LM1458Ge ICs.

Looking at the PPCB schematic the 0ohm resistor and Presence pot replace the 47R resistor to the 2µ2 cap. So disconnect the pot and jumper (0ohm resistor) and solder a 47R resistor between the positive side of the 2µ2 cap and pin 2 of the IC. You could connect it at the Distortion pot's lug 2 or...

Just to be clear, the Bee Sting is not a One Control Silver Bee. It is a fairly substantially modified Silver Bee. The Silver Bee surprised me because it sounds really good and a bit clearer than a Honey Bee. The Bee Sting is clearer still. Part of that is from replacing a single opamp chip and...

Try Antique Electronics.

I'm much the same. The Rat sounds very vanilla to me. I love adding a bass pot - that really helped. But still it's not the most engaging, complex sound IMO. I probably play the wrong kinda music for it. I have built some for friends with original round metal case LM308s and they love 'em but...

That's a LOT of corrosion!! Bloody hell - do you live in the ocean? FWIW Elderly Instruments used (maybe still do?) to sell a lot of Bigsby stuff including all sorts of parts. I would suggest getting some new parts.

A few years back Small Bear had a heap of NOS Fairchild J201s for under $1 a pop (Can't remember how much exactly but it must have been low for me to buy them) and I bought a couple of hundred. They have sat there for those years until Chuck's wisdom taught me how to use them. Since then I have...

I would still recommend splitting V1 cathodes. You won't get a true Marshall lead sound with the 320µF cathode cap and 820R cathode resistor. And if you go with the .1µF PI caps try a .0022µF cap for the first Lead Channel coupling cap. You can also experiment with the size of various coupling...

That's an interesting one - haven't seen that before. It's kind of a JTM45 with a SS rectifier.

My first thought was that it looks more like plumbing than electronics. And that's a good thing! (As long as it doesn't starting leaking like plumbing can. )

I really like the range of colours in a such a simple looking wipe. Where do you live that it's so hot right now? Obviously northern Hemisphere! It's pleasantly frigid where I am right now. I took a walk today in the rain (I love walking in the rain). It was a slow, short walk and the temp was...
