Hi,
Bit of a long shot this one, but does anyone out there have a spare power module for a Racal RA-1217 receiver?
I acquired a receiver today and plugged it in only to find it instantly blew out my RCD.After resetting the breaker and digging out my pat tester it soon became obvious that the mains transformer had failed with pretty much every winding showing a sub 100k leak to earth.....All of the connections were covered in rust so I'm guessing it's got very very wet at some point in its life and the water has got into the windings with the corosion causing the insulation to break down.
It is a sealed transformer made by BTC, part number BX-4201A with two 0-110 primary windings and a single 22.5v secondary.It will be reasonably easy to replace it with a generic one, but I'd like to fit  the correct one if possible, so thought I'd ask before modifying the power supply.
The Rx is also pretty much entirely deaf except for a small part of the 15Mhz band for some reason (I've hooked it up to my bench PSU to test it), so it has some other issues as well....
I'll look into them further when I get the power supply going, but if anyone has any spare modules, appart from the power supply, I may be interested in them to.
Cheers,Dave. S.
