Valco 510-11 in the shop

A neat little Valco, single output tube, tube rectified, one preamp tube..this thing screams when you crank it up. It needs a bias adjustment (it is running too hot as a result of todays higher wall voltages), and the owner wants an extension speaker jack..Since the amp has three input jacks we decided to convert one input jack to an ext. speaker output jack so that we could avoid drilling any holes into the vintage chassis!

Pictures and (possibly) video to come later….
