A1200 Sound Quality Issues

[klx300r]

ok so my sound problem has been solved with using my old A500's PSU but I'm noticing a 5 second delay from the time I turn power on the PSU to the time my A1200 actually starts booting? also every 2nd boot I have to ctrl-A-A to get it to boot up properly.

Checked the voltages & they seem fine at 5.2 and 11.9

Time for a new PSU perhaps?

I managed to get myself one of those new A1200 PSU's, great bit of kit, not sure if they are still available?   Otherwise just grab a 1200 supply off eBay, lots of people say the stock 1200 supplies are weak but my old one was fine.  If you're not using a mechanical HD then your PS will get an easier life anyway.

True especially as I've had this A500 PSU since 86 so it's served me well in its service life :-)
Need the extra juice so I won't b getting an A1200 PSU as I've for a real 2.5" drive, 030@50, Subway USB and fan in my 1200.

You may well find that a "bad" PSU works fine when you recap the Amiga. It's still worth doing.

You also need to check -12V it's used for sound in Amigas ...

You can recap PSU too but only if you know what you're doing ...

replaced my caps this past winter so pretty sure it's PSU noise related as hissing problem is all gone with PSU change.  Just looking for a modern A1200 psu replacment

The amiga has an awesome analogue type sound. THere is something wrong with your 1200 if it sounds like that.

seriously ? there's nothing analogue about the amiga's sound. I wish it was - something akin to a SID chip successor in the amiga would have been mind blowing in the day!
