Tube amp help-


hello all,

wondering if any of you have an idea what is going on with my amp...

the amp is a JC Verdier Audiobloc II.

it is popping fuses after I shut down the amp.

I can place in a new fuse, listen for the evening, then the next time I turn on the amp the fuse will be blown and I will have to install a new one to get the amp going again.

I have checked the following:

1. the bias is correct
2. the tubes are good, ive tried different sets of output tubes, and driver tubes and all have been tested via tube tester

thanks

Marakanetz,
1. the power output is 20watts
2. the amp is a Push Pull
3. the fuse is a 250v t2a, or as the manual says, a 2amp slo-blow
4. the amp is silent upon powering up or down
5. not sure what you are asking
6. i do not listen that loud, the amp has been trouble free for over a year now.

I did speak to Nick Gowan at Tru-sound who has suggested over the phone that the type of fuse (there are 5 types), may be a factor....

I haven't had time to look into the different types, I had just bought a pack of 5 from a well known electronic parts place where I live...
5. i just re-read question your response #5, i think all is normal when i power down.....it is just when i try to re-power, the fuse has already blown....although I get no audible cues that something has occured.
thanks for all the help, i was able to power down last night and re-start my amp this morning w.o blowing a fuse.

last nite i purchased some Radio Shack type glass fuses which were in the amp in the 1st place. ( my local electronics store only had some Ceramic Littlefuses, which may have been slightly different, which i had been blowing)

so far so good...
