Hey all, I got myself a Teac AH500i from ebay for just over £100. As soon as the amp has been on for about half an hour the right channel starts emitting an ocean like sound which slowly gets progressively louder over time. This happens on every channel apart from CD if the direct button is engaged. I have had it serviced and she replaced a transistor and thought she'd fixed the issue but I've got it home and it's still doing it.
Does anyone have any advice, is this a common issue? Any help would be much appreciated. I've now put £160 into this amp so kinda hoping I can come out the other side under £200. Would be great to go back to her with some info from people who may have run across this before.
Happy new year all. Dave
