Is it possible to get a adapter for my Bose A20 GA plug to convert to 6.35mm 1/4" Flycom jack. If possible what adapter and where can i purchase it.
Assuming by GA Adaptor, you mean Dual Plug GA Bose A20 to Flycom 1/4" Jack?
Looking on their website, they offer a Flycom Lead HA-GA/F which looks to be the product you are after? If not, drop Flycom an email and ask their advice as it's their kit?
Come back if you clarify your GA Bose is not dual plug?
Good luck, All the best,
