A CLD is merely a JFET with the gate connected to the source.Sometimes a source resistor may be included with the gate connected to the opposite end of the resistor to the end connected to the source. Bruce

The CLDs are used between he base and collectors on the output stage 2n2219 / 2n2905. I swapped them on the board with no impact on the problem. I can’t find CLDs in LTSPICE. The other diode I can’t read and it is used cathode to cathode in a weird arrangement. The diode is roughly 1/2 the length (in this case height) of a 1n4148. It measures as a diode with .51V forward. I have a hard time telling if it actually has a cathode band. I haven’t pulled it out but I guess I’ll have to and put it under the microscope to see if there is a number on it. I have a lot of very low forward voltage switching diodes and Schottky type so I probably have it on-hand if I can get a number off of it. I spent some more time on the circuit today. By the way, even though the Parent company, was General Resistance, now Prime Technology, said they would sell me a CSA, they said they won’t share the schematic.
