Tube Amp Repair


Hi

I have a Primaluna evo300 integrated tube amp

recently one of my KT66 tubes went bad, i temporarily put a EL34 in which came with amp while waiting for new tube.

Putting the new KT66 in for some reason did not seat well and guide pin broke off.  I put the EL34 back in and some smoke came out the socket.   I then put the KT66 back in.

All 4 power tubes glow but no sound.   I do not want to ship unit back to west coast

ANYONE know a firm in NJ/NYC area that can take a look at what is going on?

 

Thanks MUCH

     There's a, "key" on the side of the, "guide pin" and that fits in a, "keyway", in the side of the, "guide pin hole", to be precise (correct nomenclature).      Folks still interchange the terms, however.              

     Push a couple bare wires and/or resistor leads together with a piece of plastic and let me know how that works out for you.

                       Have a nice (imaginary) day, "Jason Bourne".

Where are you located, NJ, I'm in Plainfield, and drive 35 minutes to VAS in Cliffwood. I agree, Steve and his son Ray at VAS are terrific.

I will call VAS, I also called Bristol Electronics in HoHoKus who used to be a primaluna repair.   I checked fuse on autobias and it is ok, so i have a feeling it is a resister or something under the socket.   groan

 

btw, does anyone know who might rent or loan an amp for a few months while waiting for fix?  

I am in northern New Jersey  we can repair the amp no problem

We also build our own tube components so you can get a handle on what an upgrade would also sound like
