Yeoman tra9300

Good day to all,

I'm placing a request on here with the hope of picking up some spares for a tra9300 vhf set.

I'm looking for a vehicle rack module and leads, but most importantly, I'm looking for a good power supply board as the one I own has a fault with power regulation.

Many thanks, martin 2E0HV

TRA931X Switching & Fixed Level Audio Amplifier Board

#6656

Hi guys,

I'm bringing a TRA-931 back from the dead.

On my RF board sits a piggyback board which I presume is the Switching & Fixed Level Audio Amplifier Board.

This is though, very different to the one shown in the manual. Nothing matches, pin numbers, semiconductor count, semiconductor type etc etc.

Mine is marked CD713250, yet the one in the service manual is CD713163.
Is there a schematic for the type of board I have?

Hi Duncan thank you for the explanation so not in the UK

It’s the VAT and Duty that are causing big problems when buying second hand equipment apparently this is not the case with other items
