Title: what value are these capacitors?
Post by: JJretroTONEGOD on March 27, 2013, 11:22:44 PM
I have a mystery I need to solve.

Replacing 2 caps in an old amp and need to know the values? it says on it Philips 2u2T and other one is a Philips 1u0T, I don't know if it means 2.2uF or 22uF? same with the other one. They are both axial electrolytic type caps.

The amp is a marshall valvestate

hi, it's the valve-state VS15R and unfortunately there isn't a schematic I can find anywhere on the net, I've found all the others eg. VS30R but nothing on the 15 watt version. I emailed marshall themselves and they insisted I get them to repair it lol so I'm doing it myself. Luckily I noted down where they go on the PCB. Just in the process of ordering new caps for it.

You are correct. No need to further double check.

Cheers Stephan
