audio output transformer wiring color code

Then, while placing an order for replacement caps, I called a very experienced friend with a simple question. It has been a real education for me, and I finally decided how to tackle the project just this afternoon. I've been sweating this thing out for days, begging for help, studying, taking stuff apart, checking it, putting it back together- basically driving myself (and everybody else) insane. One of these is grounded, per the schematic.

In case you're still stymied by the power transformer wiring, blue/white will be the centre tap for the blue pair, and the green pair is the 12VAC filament winding. Similarly, a 100 uF 385V JJ can (p/n C-EC100-385) would work well for C10, though C-EC50-50-500 will likely be a little easier to mount.įor C11, probably the easiest would be to use three 47 uF 160V axials. The schematic doesn't indicate how the cans are divvied up between C10 and C12, but presumably C10 is one of the 80 uF sections and C12 is the 20 uF + 170 uF sections, plus all three sections on the second can, with C11 being the 'dynamite stick' cap, right?ĬE Dist sells a 500 uF 500V JJ can (p/n C-EC500-500) which would work well for C12.

Looking at CE Dist., (I'm a dealer) I'm not finding suitable replacements- but I'm not knowledgeable enough to determine which combinations will work, much less be reliable and safe.Every direction I'm turning today I'm hitting another brick wall. I asked about substituting combinations of caps (like a pair of 75mfd instead of a single 150 mfd) and he told me they had nothing, nor could they order something. Discrete caps inside the chassis would be fine with me, my local electronics supplier just looked at me cross-eyed and said my stuff belongs in a museum.

I pulled the caps in order to replace them, no luck in finding suitable replacements yet. It's from a model 205 Leslie, which is the same amp as the 610. Not that I am expert on Tube amps, all my instrument amps are tube, so I play a lot of them and fix what I can in them.

Not all transformer makers use these color codes, but it is good guidance if you have no clue about the transformer.You may want to add some more information regarding the Leslie amp and from what Leslie unit it is in. The typical wiring found on a lot of power and audio output transformers.
