Hi Folks - I have a 38-15 that is giving me a bit of trouble.  I have done the regular things - I have recapped it and replaced out of tolerance resistors - checked the transformers and tubes.  On the schematic,  off of the volume control (part #20) one leg is connected to between a  250 ohm 1 w resistor  (p# 33) and a 70 ohm 1/2 watt resister (p # 34). Problem is that 250 ohm resistor keeps dying (i.e. burning hot then smoking)- way too much current through it. it is connected to the transformer (p#36) center tap of the secondary winding.  I also am getting no sound from the speaker.    Attached is a photo of my work so far. I have been mindful of the polarity of the 10 and 12 uf electro caps in part # 31.  Any ideas? -- Andy
