Just to start off this info part, I find that the most common requests, especially on vintage amps, are mainly re-cap jobs, bias adjustment and tube replacement.
A need for a re-cap is often predictable because your amp will start off giving you constant background hum which will eventually turn into crackling and hissing. You will also notice that your amp just doesn't sound as good as it used to.
Of course various symptoms can have different or multiple causes, for example a bad sounding amp can be caused by badly balanced tubes or bad filtering or biasing problems or all three together, not to mention the many other possible causes. When you find that your amp is playing up on you, the best thing to do and I ADVISE YOU STRONGLY, is just to leave it turned off (or if that's a problem for you then keep the volumes low) untill you get it checked up. Solid state amps tend to give other types of problems but the approach in diagnosis is practically the same.
The only real way to find out what problem your amp has and get it fixed properly is to get your amp to a good tech and have him check it up for you and pin-point the problem (that's what I do).
Here's a short list of the various tasks and services I offer for all brands and types of vintage & modern - solid state & tube amps:
A description of the problem/s and the symptom/s your amp is giving you will contribute to a faster and more efficient diagnosis and repair. For more information and general quotes please contact me here.
I also repair vintage valve powered radios, valve powered record players, stereo amplifiers up to the early 80's provided the schematic is available.
I do not work on or repair car amplifiers, DVD & CD Players, Car Radios, Surround Sound Systems or VHS Players.
