Mark V fuse problem

This morning I decided to try a SPAX7 tube in V1.

As soon as I flipped the power switch, the fuse blowed. The tube was brand new.

Is there a way to install those tube ? How did I have f..cked it up ?

I don"t have another fuse handy. I tried a 2amps one from my F-50 and it burned too.

The tube can only get in there 1 way right ? I mean the missing pin is pointing the front of the amp.

Now i have to wait for Boogie to ship some to me from Cal to northern Canada because those fuses are nowhere to be found inside a 700km radius from my house.

That sounds like the tube you installed is shorted. Always a bummer for a new part to be bad. Good luck to you.

Yeah...bad tube unfortunately.

Be careful with new fuses too. I got one of the AllParts fuses and it never seated properly. I seem to recall it was too small. It made the amp cut out intermittently.

A quick update , the amp is up and running.

Somehow my V1 install had the consequence of taking out the rectifier tube. I don't know how it can happen.

I still don't if that SPAX7 is good or not. Waiting for a spare 5U4GB to test it.

Thanks for reading.
