Yes I expect so Alan, although not as much of a problem as for the owner of one these 5 valve A22's when the dial bulb needs replacing.
Since the fifth valve occupies what was the removable bulb inspection cover, the only way to change the bulb is to remove the knobs and take the chassis completely out of the case.
Then the dial needs removing, which means the use of a long shafted screwdriver through a small hole in the side of the chassis to loosen its fixing screw.
After the new bulb is fitted and the dial back in place the dial then needs rotating to the correct position to make sure it is aligned correctly with the tuning arm. That means powering up out of the case to cast the illuminated pointer on the correct point before tightening the fixing screw again. Then the chassis can be refitted back into the case and the knobs put back on.
Not too much of a problem for one of us or a service engineer of the time, but for the average owner - not without danger and quite a faff to say the least just for a bulb!
Regards
