Carlsbro PA60 '71 valve guitar amp - EL34s; modified to plexi style

This is approx. 1971 Carlsbro PA60 in very good condition for the year. There are nicks and scratches in the tolex and some of the "smartie" coloured knob centres are missing but it looks the business. The amp is working great.
It has Siemens EL34s fitted which sound wonderful and British mil spec ECC83/12AX7s i.e. CV4001.
The Carlsbro PA60 uses the same transformers as Marshall in this period, so it is sometimes known as the poor mans plexi. However the PA60 inputs are not designed for gain or pushing with boost pedals, so this unit has been modified to Marshall plexi style input sections. 
One channel is super lead style, less bass and more drive.
One channel is normal plexi, more bass, less gain.
The two channels can be jumpered together with a switch, and then both blended to taste. See the video and you can hear the bags of crunch and growl available.
Third channel is low gain, suitable for bass guitar, or a clean guitar. There is a foot switch for adjustable boost, footswitch is included. On the back there is a switch for negative feedback giving "marshall" to "bassman" flexibility. Back off the gain and the amp can do lovely cleans too, and works great as a pedal platform.
But it's made to rock. I would recommend pickup and you can hear it for yourself, but I can ship.
The Bulgin power connector has been removed for the modern IEC, electrolytic capacitors replaced, and old stock mustard and RS caps used in the signal chain changes.
