SERVICING A LINEAR L.50  AMPLIFIER

Again, a genuine factory assembled L50. This was pretty much the biggest daddy of all the Linear amps. The Power transformer is massive, yet really it is under-wound with cheap copper wire and it is very much on the border-line when it comes to the current rating capacity of the said wire. You would be hard-pressed to get more than about 42 watts RMS from one of these!

Most people with tired Linear’s don’t want to bother about a full re-furbish….full strip-down/re-spray etc. They are usually quite happy just to have them back to life…….no problem….Job done!

Speaker jack previously fitted…..makes sense on these instead of those silly little banana sockets!

Side-mounted input jacks, again previously replaced instead of the co-axial sockets that were fitted as original.

You wouldn’t be allowed to have loosely riveted fuse holders & everything exposed to electrical shock if this was designed nowadays!

A damn good few components changed on this one!
