From memory there ate no electrolytics.
To be honest it's probably your ULA, which means you need a new If1.
If you're lucky it'll be one if the many transistors, though! -

If it turns out to be the ULA, perhaps you could sell it to Stephan? You can send it to me and I'll check the ULA and remove it if it's ok, then fit the working ULA to Stephan's IF1 and send it back to him? -

IF1+kempstoncan IF1 be used with standard kempston adapter for joysticks?
Back in the 80s I was using a standard Kempston interface combined with an IF1 and microdrive all the time. Never had a problem. Don't know if other kempstons having cart slots will work though... -

Actually, scrub that.
I just looked at the schematic and the IF1 uses a totally non standard pinout anyway. You'll definitely need a special adapter cable. -

Paul Farrow is a master of RS232 and he will also help you with any questions or projects you might have. For the IF1 you don't need to add another cable. You just need one, wired right (I think). :-)
@fog: yes. :-) -

I wasn't aware of a Multiface variety with a PAL (but I only saw IF1).
Can you get a pic of both sides of the board before you try to repair it

I have a problem with a IF 1.
If I type a IF1 command, the spectrum hangs. Nothing more is connected than the IF 1 to the Spectrum. -
