I see where you are coming from,but surely any amp is worth bringing back
from the dead,they had a reverb channel that sounded pretty cool. :)

Each to his own. My time is to valuable to expend on repair to any solid state guitar amp other than a Lab Series L5/7/9/11. ymmv... 8)
AS I get older, I make my decisions based on value and function versus time and trouble. A Lab is worth the trouble with regards to sonics when correct. No other solid state guitar amp gives my ears what my ears want to hear. :2cents:
good luck with it.

Hi Dean jnr, i get your drift,i have a few classics..... Orange OR80, Fender Twin, Vox AC30/4......
they are all fine amps,just need to get some of these "clunkers" as i call em out of the way.
Theres a bit of info out there on Londoner amps but not much,thanks for the reply :)

Many vintage transistors amp schematic are not available .
Some not available for free can be buy for $20 at http://www.musicparts.com/companies.asp

No Londoner !

Schematic and parts for Vintage or modern tubes's amps, like your Fender ,Vox...are another story.

And....just as with tube circuits, a good tech might not need a schematic to get that am p going. Things are just much, much harder without the schematic...especially since the solid state circuits are PCB technology and that increases the difficulty in tracing things out.
