The Heyboer Tx we have has a 5V CT for the rectifier's heater. When hooking this up, is it one leg of the 5V and the CT (ie 5-0 of the 5-0-5 winding)? The second leg is not used, correct?......Colin

The 2 yellow are for the rectfier heater. for now don't hook the CT( Y/W) to anything. for a normal full wave rectfier you do not need to ct the heater. Let me know what rectifer you are useing as as to what pin to take power from. I am working day and night at the mines. I am sure Douglas will answer if I can't get back to you...JohnPS. I did get the CCS wired up will try to post a pic when I can

Looked at several schematics. If using a indirectly heated rectifier (5AR4), you can either tie the heater center tap to the cathode which is connected to the (+) side of the filter. OR, you can omit the center tap connection all together. I've seen both in some highly respected designs. If using a rectifier like GZ34 where the cathode is tied to the heater internally, or a indirectly heated retifier, then the (+) side of the power supply filter is fed from the heater center tap. Joe

Hey-Hey!!!, Been out salvaging some old broadcast stuff. Heavy and bulky...On to your question. You can either hook the choke input leg up to the CT or you can leave it be( disconnected, but insulated and secured ) and hook the choke up directly to the cathodes of the rectifier. See Damir's drawing for the 5V ( 5V4, 5AR4, 5R4...)and 6CA4 9-pin connections. If you stillhave questions, I'll be about. regards, Douglas
