Hi there. I've completely re-capped my Quad 99 Pre-amp with new, low impedance low leakage devices. All is well.
However, on the board, I noticed some electrolytics rated 10uf at 50v which were green in colour and clearly have no "+" or "-" [on the cap or the pcb]
I'm making an assumption they are NP electrolytics ? They are physically the same size as the standard electrolytics on the board (I replaced all 10 of them plus plenty of others...)
All of the caps I changed were in the power supply, but these look like they are in the signal path.
Assumption 1:- If I change the cap value, something might happen to the sound
Assumption 2:- as they are in the signal path, that is not always a good thing
Assumption 3:- I can bypass... with a link.. but it's a risk
If I wanted to "upgrade" the quality of the cap, what type should I shoot for ? Tantalum ? Polypropelyne ?
Any thoughts ?
