When you look at the pins at the bottom of the 300B tubes not that two are larger and two are smaller. Make sure the pins are plugged into the right sockets based on their size. This is a very common mistake. However at this point I wouldn't mess with the amp again until a tech has looked it over. No point in doing further harm to either you or the amp.
Help Smoke rising from 300B amp
Hi all. Happy New Year!
Can anyone offer advice as to what I should or can do?
My situation: I just came into possession of a used 300B integrated amp (Audion Silver Night (single-ended) 300B) which is a few years old. I read all the reviews I could find and the manual on the Audion website before doing anything. I put the tubes in the way the website and other photos showed and the manual indicated, and put the EC88 and 5687 tubes in the right sockets according to the manual. I hooked up interconnects and speaker cables and plugged it in (volume knob set at zero).
I turned on the switch and after a few seconds, acrid smoke started rising from the amp (through the holes around the tube sockets). I immediately turned it off, unplugged it from the wall, took out interconnects, and took the speaker cables off at the speaker end. There it sits.
My wife was petrified. She asked me to seek help before touching it further.
Safety first -
Can I touch the amp (metal chassis) without worry of electrocuting myself from current still in the caps (or any other reason)? Are there any safety precautions I should take in handling it in the immediate future which are necessary because of what just happened?
Second -
What did I do wrong? Anything? Everything? Despite my research, did I put the 300Bs in wrong? Any ideas?
Third -
What is likely to need fixing/replacement?
Thanks
Travis
