Is anyone aware of where I can find schematics for early (below 25000 sn) FT-101's? I have a copy of the Yaesu service manual but as far as I can tell all the schematics are for B models and up.?

Thank you! I'm well aware of Fox Tango.

 

Thank you but I already have those manuals. As far as I can tell the schematics are all for B models and newer. Am I missing something??

 

Hi,
????? ? Attached is a pdf of some of circuit details of the early model FT-101 Serial No. < 25,000 (I have that model).?

a) The main circuit diagram attached, is for the early model FT-101, note the internal details of the plug in modules identified as 'MJ(1), (2), ...' are not provided on that circuit 'assembly' drawing, but the interface pins of the plug-in circuits (MJs & PB numbers) are provided.?

b) The numbers of the plug in modules for the early model to look for (early model) are PB-1077B for the main receiver RF plug-in PCB, High Frequency IF Unit (PB-1084C) and the low frequency IF unit PB-1080A, for example. If the circuit diagram does not reference the PB-1xxx numbers listed, it is a circuit diagram for a later model.

c) The Fox Tango site does have a readable pdfs of early model circuit diagrams with circuits of the early model plug in modules included.

????? ? I hope this is of help.

Regards.
