[QUOTE="Gohde, post: 1071010, member: 24319"] Thanks all for the suggestions and offer for help too. As a bit more background: Bought the amp on FB and after seeing burnt out resistor and hearing a hiss, I dropped it off at my local repair shop. [url=https://postimg.cc/KkdqZv6n][IMG]https://i.postimg.cc/NF0WkKbP/326-DB47-A-440-B-45-CD-A5-FA-FF904-A427764.jpg[/IMG][/url] I think, because the resistor was a visible issue, it was fixed (together with 2 caps that didn?t measure well). It came back, but the hiss was still there. I?ve taken it back, but wanted to see if people have had similar issues, just to avoid being something unrelated being fixed. I?m not knowledgeable enough, so if this would have been quite clear as an issue I could have given some advice to the guy fixing it (and also avoid any inaccurate explanation of what has been done and why). Once it?s back I?ll report on whether it?s sorted. [/QUOTE]
