Once again, thanks. So much knowledge, so much experience on tap.
Is it time to retire the AC50.....maybe. For younger readers, VOX, along with Marshall and to a much lesser extent were the amps to have in the 60s. VOX also produced the Continental organ and a short lived range of guitars. The AC50 even has its own website http://www.voxac50.org.uk/
Here's a couple of photos.
In answer to where am I, I live in Richmond, Surrey, not far from the much missed Chandler guitar shop.
Very best wishes and thanks once again.
Chris
