Need info for ordering trannies for an express proyect

[Silvio55]

Hi! I´m going to start a proyect, an express clone, or al least an express inspired amp, I live in Argentina and I need to give the guy who makes the trannies some specs. As far as I know I need a PT with 300-0-300, and a the OT some has 5K2 primary and others with 6K6, but that´s all I could find so far. If someone could tell me more specs I will be grateful, thanks in advance!!

See the diagram below.

300-0-300 PT 50w rating at 300mA and filament 7.5A
280-0-280 is used by many

6k6 OT primary 4/8/16 secondary

Thanks M Fowler!! Another question I have; the OT should be like a standard guitar amp tranny or more like a HI-Fi style?

[M Fowler]

I would think guitar type. See below
