Are there any AR88 enthusiasts in Australia on this
group?

Anyone (in any country) know anything about the RAF
variant (R1156A I
believe)? It appears the same as the normal one except
has an earthing plug
for the mute fitted to the rear (a plque syas fopr the
Control Unit type
88). I've just acquired one with leaking bathtub
condensers.

Where do the AR88 people hang out please?

I was aware of both!

The bathtub caps can often be "rebuilt" if you want
something original looking. You need a large soldering iron
to get the bottom off. It isn't a matter of heat but of mass
to be able to get the thing off. They were probably soldered
on by dipping in a solder pot. Once the bottom is off you
can melt out the potting compound. Most of this is a wax
mixture which will flow out. Most of it smells pretty bad so
do this outside. The original cap can then be removed and
replaced with a modern one. That can be held in place with a
bit of silicon rubber or even some of the original potting
compound melted back in. The bottom can be tacked back with
the soldering iron.
I think this is a lot of work in the interest of
appearance but a lot of people care about that.
If you have one bad electrolytic look our for others of
the same type.
