Hello Everyone
As the subject said and I need some help for a dufus, please.
I wanted to listen to some youtube stuff and got no sound. I played a record (selected Phono) and got sound. For youtube and other computer sound, I use "Spare" which is the problem.
I touched the cover and it felt very hot - much hotter than usually - more or less directly above those 6 tubes. And I switched off immediately and removed the wallplug.
This amp was rebuilt about 1 year ago by a local tech who imo did a very good job. Somewhere on AK are pics of the restore and about a month ago, I heard some very faint crackling a minute or so after switch on. This sound disappeared after about 2minutes after switch on and maybe I should have taken this as a pre-warning of something going south.
I am a total novice diagnostically but can solder very well and replace parts I can visually see overheated and the tech which did the rebuild for me is no longer available.
All the fitted tubes are still Dynaco-branded originals, btw.
Tomorrow, in daytime, I will take off the bottom cover, have a look and take some pics incase I can see the origin of overheating so much.
Please help.
Cheers all
