volker hois All Messages By This Member #119644 Hello Dave, thank you first for the upload! Incidentally on page 145 is the power-supply 'A1' but no circuit sheet. I must repair on the board itself not to swap out the board. Well I repair on the board itself so I do that for more then 35years - maybe you have a real service manual and not the how to do swap a board plan. 73 de OE1DOA Volker Am 25.10.21 um 00:47 schrieb Dave McGuire: toggle quoted message Show quoted text On 10/24/21 6:38 PM, Dave McGuire wrote: ??

volker hois All Messages By This Member #119652 开云体育 Hello Yves, thank you for helping - but this is a service guide and I'm searching the circuit sheet to repair the power-supply but there is no sheet include. maybe you know where I can get the Service Manual and not the plan how I can swap a board in the rack.

What you're looking for is the CLIP, Component-Level Information Package, which includes the schematics. I've never seen one available for the 54720D, but perhaps someone else knows better. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
volker hois All Messages By This Member #119760 Hello Dave, yes shure I'm searching the Circuit sheet plan. I found out that the Resistors (22Ohm) positions 14,15 are interrupted also the Transistor (2SC3866) position 50 is short and the Z-Diode position 57 is short. What I would like to know is the Z-Diode value? I guess that is a 6V2 or 7V1 Z-Diode - I should use a crystal-ball for this information. I've never a power-supply like this where is no schematic circuit plan. 73 de OE1DOA Volker
