Hi,
I recently found an old HMV record player in a shed, so i decided to take it home with me. When i plug it in, the turntable spins fine, and i can adjust the speed of it with no problems. However, the speaker does not come on instantly, it takes about 10 seconds for it to power up, but then after about another 5 seconds the speaker shuts off and the turntable keeps going. Then, after another few seconds, smoke starts to come out from the circuit board.I took off the panel that was convering the board and plugged it in. It seems the valves on it (there's 3) heat up fine, because there is a glow from them and that the smoke is coming from the variable resistor for the Bass. I've tried drying it out with a hairdryer and i've cleaned it out completely, but i have the same problem.

Any suggestions would be greatly appreciated.

Thanks in advance.

EDIT:
It's not the variable resistor, i removed it and there's still smoke. Now i think its the valves heating up too much and melting the board.
