Are the noises on both channels ? If yes I would suspect a power supply issue. ie. noisy regulator transistors.I have been playing the unit for a couple of hours now. Every once in a while I get a pop/short crackle. Like every 10 minutes or so.
I will change the 458's on the amp boards when my BP caps come.
Any other suspects?
How about on the PS board?
i would check the soldering first and clean the fuses/holders
Well I didn't shit or giggle but the reflow seems to have worked.Especially check the solder connections of TR701 and TR704.In fact I'd reflow them just for shits and giggles.
