[QUOTE="mafioso, post: 574337, member: 572"] Hello Ampdog Apologies for my silly post. I bow to your superior knowledge about valve amplifiers and still have difficulties distinguishing between capacitors and resistors. I have a Stereo 20 schematic and will have a look later to see what I have at C5. The other thing which bothers me is that resistor which is supposed to desolder itself in case of trouble. How does it do that, even if it gets so hot that the solder melts? If the resistor overheats and causes the solder to melt, it will obviously not desolder if the wire ends are bent over at the tags. IMO it will also not desolder even when the wire ends are kept straight and pushed into the tags without bending them. I learned late last night from a fellow forum member that a wellknown Jhb restorer we all know also uses a fuse in this place for better protection. Regds skollie [/QUOTE]
