I ordered an ANOS Tungsram 12AX7 and put it in the AC30C2 V1. When powered up and all, no sound. I go to take the tube out to try another one in V1 and I notice that one of the pins has now broken off into the tube slot. Fun. The broken pin, when looking at the tube with the dead position up, is the pin first to the right. It is labeled 1 from the diagrams I see online.

Two questions:

Did I damage the amp for running it (about 30 seconds) with the broken tube in?

and

What is the best method for getting the pin out? I cannot see it physically sticking out of the slot so I am afraid I may have to desolder the slot. I am afraid I will burn the circuit board and my AC30C2 will be no more. :c

The tube pins look kind of aged like a dull gold. The bend pretty easily too. I am going to contact the seller and ask for a refund.

Is it possible for you to push the pin through with something thin? Maybe if some of the pin is protruding you can get it with tweezers.


I dont think you broke it by not running a preamp tube. I dont think its damaging like forgetting a power tube or something.

The socket is soldered directly to the circuit board. The only opening is where the pins are supposed to enter. I have not tried poking it yet, I hope that will work.

If its soldered to the PCB you wont be able to push it through probably.


Im thinking youll have to wedge something small under it and try to coax it out.

I called a local amp tech and he suggested to just try to put another 12AX7 in. Either the pin of the ANOS fell out (I couldn't see it in the slot) or it was far enough out the other side that the other tube could push it out. One of the two happened, the amp is back in working condition.

Sad about the ANOS though. I had been really excited to hear it. The supplier apologized and will be sending another tomorrow, I appreciate that.

Glad you got it sorted dude


Sucks about the tube, but at least they're hooking you up.
