I do a lot of Valve amp Repairs and have had that happen on a couple of occasions & i suspect that a 450 Volt cap is going to make a bit more of an impact than your wee chap.<br />BTB many years ago i was the service rep in Australia for SCI EMU Korg Alesis Ensonic and worked on all the rest inc Fairlight Roland Yamaha and all tho loth to remember even electric accordions (I still shudder).<br />I still have Service manuals and some parts in boxes so if ever you are desperate wont hurt to ask. davfew@gmail.com<br />enjoyed reading your Blog.<br />df Anonymoushttps://www.blogger.com/profile/04886780765724142596noreply@blogger.com
