Here’s a restoration project for the amp builders out there. It’s a Moody GA 35 all valve amp originally built in Sydney around 1961-62.
It’s not in its original configuration but we’ll tell you what we do know –
The amp should be wider horizontally than it is high – see pics of an original GA35. But this one has been turned on its side so it now sits taller than it should. Why you may ask ???
There is probably no reason apart from being the product of experimentation by a mad amp-scientist on a binge of mind altering medication during the psychedelic era. Or maybe it was the post apocalyptic era ? Whatever – it needs fixing.
So it deserves some TLC from someone with the know-how patience & dedication required to bring what should be a great amp back to life. All the bits are there – just currently all packed in the wrong way around.
The original cab could easily be set up horizontally as it was meant to be. The screw holes for the caster wheels are still on what should be the bottom of the cab. The factory cutout for the controls is still in its original shape and the chassis could certainly be relocated there as it should be.
Naturally it’s gonna need a new tolex skin and some other cosmetic attention but it’s all do-able.
One speaker is possibly original and the other is a very early Etone 12”. They are both working.
This is a very early version of the GA35 where the single 6″ MSP speaker is not a high-frequency driver or ‘tweeter’ but it is actually the reverb speaker. Much like early tonewheel Hammond organs the reverb is a separate small amplifier which then feeds its own separate speaker. However on this amp the reverb and tremolo circuits have been disconnected but could be reinstated.
The power amplifier which should be located at the bottom of the cabinet comprises 2 x EL-34 output valves and 2 x 12AX7s. The amp is actually working but it sure could sound a lot better with a good going over.
We have heard an original Moody GA 35 punching out a fat 35 watts and it is a mighty good sound. We have seen original and restored GA35s selling for over $1500 and they sure aren’t making them any more …..
All in all this is a potentially very rewarding rescue mission for the technician with the vision to restore an early Aussie classic back to its former glory.
