WOW: I wonder where that has been hiding its Fantastic.
Kev I wonder now that you have opened it could you verify the two biscuit tuning capacitors for me ,it would be much appreciated.These are the two brown ones coming off the band selector,the one's in mine are (.0005 and 0.002 )these had been changed sometime and think they may not be correct value.I have notice that the trimmers are different than on others so it may have been made special for more reliability.Regards Gezza.
PS:as the guy's have said keep it as it is there may never be another so it could be very very colectable in the future.
