Gibson Goldtone output transformer

[Tiny_Daddy]

This amp has a shorted Drake output transformer #29513 so I am not able to measure the original turns ratio. Output tubes as marked on the chassis may be EL34 or 6L6GC. B+ is 430 Volts. As a replacement I am considering transformers from Marshall JTM45 (7371CT primary) or Marshall JCM800 (3200CT) primary. Which would be best?

Those were built by Trace Elliot before Peavey became the US Trace Distributor. I've emailed the British Trace-Elliot company for parts and they've referred me to British Audio Service as their parts distributor in the USA.   

Here's their parts department email if you are looking for an exact replacement. parts@britishaudioservice.com
