SERVICING OF A CARLSBRO 50 TOP AMPLIFIER HEAD

Whilst I already had a Carlsbro 50 Top on the site (the one rescued from a skip! Please see here: http://www.chambonino.com/routework/routewk21.html) It was however a little sparse. Note the non-original pointer knobs on this one. (These were normally coloured “smartie” knobs.) I replaced these for the customer accordingly.

All the main board has to be removed to access the nuts and bolts….in-order to remove a faulty transformer!

All back in place. Note the added extra 60uf @ 500 volts main HT cap. This stiffens these amps up really well……as-in most Fenders too! Also included is a bias pre-set pot (normally a fixed value resistor on this model).

I think this power transformer really has reached it’s “sell by date”!
