I have a Croft pre and power amp. I had the ffffff noise from one speaker, dropped the amps off for Glenn to service, the tube had reached the end of their lives, had them replaced. Sounds amazing now. However there was no loss of volume Glenn described it as a noisy valve!
How do you know when tubes are done?
I have a homemade pre-amp and amp - both tubed.Recently, it became necessary to turn the volume up quite a bit to get the same sound level.It still sounds good but I started to wonder if a tube or two was the culprit. The tubes are about 8 or 9 years old and get light to medium use.
Suggestions?
