The 6GU7 is a 6-volt version of the 12BH7 and has the same pinout pattern as the 6922/6DJ8 family of tubes. However, the parameters are different (6GU7 has half the amplification factor and twice the plate resistance of a 6922, and draws more filament current.)
You may or may not be able to sub a 6GU7 for a 6922 in your unit. I suggest contacting the manufacturer first if you want to try. 6GU7s are much less expensive than 12BH7s on the NOS market, and Jim McShane among others has good ones, e.g. GEs.
