Here are some photos.  I unplugged the speaker from the amp when I tested it.  There is a photo here that show the plug removed from the back of the amp. Hope this helps...thanks!

I took my meter set it on ohm.  Attached red to red and black to black on the speaker and it read about 7.8?  Then I put one to the tip of the plug and the other on the other end and got a similar reading?  Do not know if this is the right way or shows the speaker plug works.  I will take everything apart when I get a chance and see if I spot any other fuses.  Will also upload photos...thanks!

Yep....plugged into my small Peavey practice amp and all was good.
I was wondering...even if the input jack for the guitar was dirty, if I tap the tubes I would get a sound...I get nothing.  Thanks for you advice!

The Newcomer's Forum / KMD GV60 Guitar Amp....RIP?
June 10, 2012, 04:56:25 PM
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
