Hi,
I have a KMD GV60 guitar amp I bought nearly 25 years ago. I believe it has a solid state preamp and tube amp. It has Sovtek 5881/6L6WGC Tubes.
I am a casual "hack" player and the amp has never really been used heavily. The last time I used it was about 1 1/2 years ago for about a half an hour with out any issues at all.
I decided to attempt to start playing so I plugged it my Strat and fired up the KMD and got nothing.....no crackle, no hiss, nothing from the speaker. The power light goes on as well as the light on the footswitch works. When I look at the tubes there is a very, very slight orange glow from where they attach to the amp and after awhile they did get warm. I tried a different cord and guitar to the same consequence. I took out the tubes and the connections are clean and the tubes do no look fried. However, it may be close to 10-12 years since they have been changed. I have only used the amp a handful of times over the last few years.
The speaker connections are sound and even unplugging the speaker input does not elicit as much as a whisper.
So.....my question is where do I go next? Could the tubes go bad just by sitting? Since the amp is worth about $200 in working condition is it worth fixing?
I am no expert so I thought this would be a great place to start. Any advice or comments would really be helpful.
Thank!
Mike
