Hi guys

On the market for a new valve amp and was looking around for some second hand dealers so I can check the state of the amplifier before buying them.

Ran into a brick wall on gumtree (as most of the ones I'm looking at such as the blues junior 3 and AC30 no one wants to get rid of!). I won't even consider touching ebay, too risky

Could anyone suggest second hand amp dealers in the london area?

Apologies if I missed a similar thread.
