Hello everybody,
A few months ago, I've bought a second hand mark v 90 w head and I after a while I have noticed that both the lead channels weren't able to make a saturated sound which it could be expected when you rise up the gain knobs so I decided to replace both power and preamp tubes and I went to a store to compare my ampl with another new mark V amp using the same speaker and cables and I noticed a really big difference between the two as mine wasn't able to make the same type of saturation sounding like it was a slightly distorsion making the same volumes and tones set up.Also the shop assistants did noticed the difference and the lack of saturation. I am in Bangkok Thailand and the amp has been inspected already by 3 technicians including some from the Thai dealer shops but they weren't able to solve the issue. I was wondering if somebody could give me some hints if this is a common problem for older amps, I think the amp is already 8 years old. It sounds like that raising the gain knob mostly increase volume instead of saturation and when we did the comparison with the other new amp, it was able to deliver a much more saturated sound once you were raising the gain in both channel delivering a much more powerful distorsion.Caps and knobs and also other elements have been inspected is there any possible reasons that can cause this problem?
