Congrats on the fix. My se30 just got the wiggle jiggles but works ok so I need to recap the analog on it and a classic.

I replaced the C1 capacitor with a new one from digikey, the machine worked for a day and then something went in the back and it was dead. I tested everything i could think of and finally replaced the Q3 horizontal power transistor. The Plus now seem's to be working ok. Which is a little odd, as after doing the repair. I tested the old BU406 transistor and discovered it wasn't faulty. No idea what is going on, but things seem to be ok.

It says to replace it with a 50v or greater capacitor and that it HAS to be non polar. The only thing it doesn't mention is the UF rating and i'm not savvy enough to know if thats important in this situation or not. Btw can someone please confirm for me that i've replaced C1 with a suitable component. I bought a 10uf 50v non polar capacitor to replace the possibly defective one at C1. Shouldn't it be 3.9uf? I think the original is 3.9uf. - Dylan It doesn't really matter as long as it's not too small. I used four (4) 1uf monolithic ceramic caps in parallel to avoid the whole electrolytics category. - jS -- -- ----- You received this message because you are a member of the Vintage Macs group.
