[Amps] High Voltage FWB Rectifiers

[Charles Bibb]

I'm parting out a retired commercial FM transmitter that was given to 
me.  It uses an 8877 in the final.

In the power supply section it used a HV FWB rectifier module.  The 
module is "house marked" and I cannot find any correlation or 
cross-reference to those numbers.  In the transmitter manual, someone 
had penciled in on the PS schematic that the module was rated at 
1.5A, 7500 V.  Type number was given as BF3645, which I also cannot 
find a data sheet for when doing an Internet search.

This one checks good, and I'll likely use it, but I'd like to know a 
source for a replacement.

Does anyone know a source for buying one of these or a module with 
similar ratings?  Any info would be appreciated.
