I installed one in the ER15, (the other being a spare), connected up the speaker and guitar and turned on! There was no big bang – which was a relief! The ‘On’ light shone and gradually the heaters all glowed gently. After what I thought was long enough for everything to warm up I had a moment’s disappointment! I couldn’t hear a sound from the speaker, not the slightest hum or buzz! As I reached forward to turn one of the controls I must have brushed the guitar strings, ‘cos the room suddenly filled with guitar noise! I played a few notes and a large grin spread across my face! It sounded wonderful! I played with the controls – no buzzes, pops or bangs – so they seem clean. I then tried the second channel and that sounded the same! I’ve been playing with it for most of the day now, and it seems to be working perfectly! I’ve reinstalled it into the case and tried it again.......perfect! All I can say is that I’m very pleased with the result! I phoned my son and left a load of guitar noise on his voicemail!
John – I think this is now the time to thank you as much as I can for the help you have given me. I am absolutely sure that without your advice, support , knowledge and skill I would never have been able to get this amp functioning again! I hope you won’t mind if I contact you again in the future – this amp actually belongs to my son, but I want one of my own now, so I may have to repeat the process! If I do, I’m sure I’ll need your help again!
Thanks so much! Colin."
