Sony SL-C5 Betamax capstan servo issue FIXED! 

me alegro mucho que lo hayas podido reparar

Given the high-resistance environment of the servo IC, I wouldn't care about the internal resistance of the capacitors. This means you can also replace tantalum capacitors (nowadays about 0.1-0.5 ohms) with low ESR electrolytic capacitors, ceramic multilayer capacitors or cheap film capacitors, and you don't need 2 tantalum capacitors to simulate a bipolar electrolytic capacitor. But you shouldn't ignore transistors either, because when you look at the minimum amplification factors, I'm surprised that the circuits always run. But I don't know whether SONY provides sufficient transistors without extra marking of the gain factor or whether it depends on it in the final test. In any case, I find 80 as the minimum amplification factor between two “independent” video stages rather economical.

😮

I have the same issue on my JVC GR-C1 VHS-C camcorder, it plays tapes way too fast like it's in picture search and there are noise bars in the picture. It's not as bad as this one. The unit was working fine before I reassembled it and I even made a test recording successfully. Could it just be a dirty control head?
