I am involved in the refurbishing of an Armstrong
A220 valve amp. Jim Le Surf started his illustrious
career with Armstrong Audio, and has been able to
supply me with some good data on this amplifier from
his website.

The amp on my bench has been well and truly
"improved" over the years. There have been step circuits added
(presumably to improve stability) with the addition of gold plated
speaker terminals, and a ground screw, plus the IEC connector.
Some aluminium plates have been fitted to the rear panel to hold
these modifications. To help me to return this amp to its
original state, I am keen to know what the rear panel looked
like originally.

If anyone has such an amp, has access to one, or has pics of
the rear panel, both Jim L and I would be most interested to see
them.

Any info would be appreciated, either to this thread or by
e-mail to me at

Thanks in advance
Iain
