Hello everyone! Today there was such a situation with my Diezel VH4, after pre-warming up the amplifier turned on and slowly the volume began to decrease to a certain volume. On all channels, the volume dropped significantly, while the overload on channels 2, 3 and 4 decreased. I'm trying to find what this problem might be related to, (I don't think that it somehow influenced the decrease in the volume of the amplifier, but nevertheless, before turning it on, I accidentally connected Delay pedal by plugging it into both "return serial parallel" inputs).
Thank you very much in advance for your reply!)

Corrosion in the serial jacks.
I had this happen to my ‘00 VH4.
Best to take it apart and clean up the jacks or take it to a tech.

I think that the problem with quiet sound may be due to the fact that the tubes in the preamplifier have come to be replaced.

I just had this happen to my ‘95. It was exactly that-corrosion in the serial jacks. Cleaned them up and good as new...I should note that I originally thought it was a bad preamp tube but after rolling some tubes the problem still persisted and thusly discovered the real culprit...this knowledge is worth it’s weight in gold
