When mine caught fire, they had to fabricate two new boards I believe. The closest transistors they could get to the originals had higher gain and were thus more prone to self-oscillation (the malady

Normally it is not the entire dial cord which needs replacement. There is an elastic "bungee" section which pulls the pointer down to the left. Over time that bungee loses its elasticity. The section

We have several CVS stores in Johnson City (northeast Tennessee). I went to two stores and found one headphone set at each. They have probably taken them off the market because they cause lead poison

Oh, no! Headphones can pick up RF from a nearby transmit antenna and cause blinking LEDs on your rig. Heil headphones did that for me.

Dunno the problem but would suggest checking to make sure the ALC light is working on other bands. If the ALC doesn't work (usually because of bad diodes) then the PA can oscillate. If this happens,
