A500 Modulator fault or want to trade for working PAL A520
I've just picked up an A500 1.3 and the original owner stated it was in working order. Aside from the fact I only paid £11 for it the modulator only outputs in black and white (tested modulator with a working A600). I have tried tuning the A520 using all 3 turny things inside it but no luck.
Does anybody know what the fault is? If it's not fixable I'm willing to swap for parts I have (A500 mice, PSUs, floppy disk drives, blank disks, Commodore 1084 monitor lead - these things are rare  ) for a working PAL A520.

I could loan you a working modulator for you to try?
Where abouts are you in the UK? Dave G

If you're willing to pay postage both ways - I can loan you a known working modulator to test your theory with.

Re: A500 Modulator fault or want to trade for working PAL A520
For anyone else with the same fault - the modulator was duff. I picked another up from ebid for £5 incl. postage, rehoused the internals into the original 520 (better enclosure).
Now how much could I get for a working, non yellowed, boxed 1MB PAL A500 1.3 and extra boxed games (UK postage only) ?  No Workbench disks tho  BTW did the 1.3 A500 ever come in the Cartoon Classics pack - I know the Plus was swapped when C= started running out of A500 stock but was the change over in this set?
