came from a friend who is a member of Women of the Night
brought this back to life for a friend. someone, probably more than one person seemed to try it before. but it sounded dull when it came to me.
BF champ AA764
the voicing of stock 8″ speaker is quite different to 50’s Oxford 8EV. I guess this stock speaker came from Oxford as well but I could be wrong.
I replaced the stock 25uf 25v power tube cathode bypass cap to 47uf.
it came with stock Amperex buggle boy which is still alive and kicking and GE 6v6gt. only the rectifier tube has replaced at some point.
stock speaker is on the right side.
I met this little guy again this morning. and gave it RCA Command 5751 as a present. I’ve tried more than a few 12ax7 tubes with this Champ for a while. and love the sound with this 5751. and, one 6v6gt from Valvo factory in Frankfurt is coming to me for this Champ.
the 3rf filter cap is Sprague which replaced the big 8uf 500V Astron minimite last winter. it still has the 2 prong power cord even with the death cap. this 57-year-old Champ is beautiful and sounds great of course. but didn’t sing as much as my ’59 Champ till this morning. now it does sing like a magic.

You will have a grand orchestral experience.
did a simple job for a friend. he has some extra 50’s Jensen speakers and wanted to use them with this GT40 amp.
he told me GT40 has mono and stereo output mode. so, we decided to leave one of the 6.5″ speakers as it was. then put a long thread 1/4 jack on the other output.
the only place I found for the internal/external switch was the inside of the bass reflex vent on the back. the back panel itself is too thick to attach the switch.
