REPAIR & SERVICE OF A SHAFTSBURY MODEL 519 COMBO AMPLIFIER

 

 

Hi there. This Dallas Shaftsbury 519 combo came through the workshop for a general service and a non-working tremolo. Like many amplifiers of this age, it needed most of the smaller coupling capacitors changing, although all the electrolytic's were fine.

After carrying out the work, together with all the normal service requirements like spraying the dry, crackly potentiometers etc, the amp burst into life complete with a super tremolo. This amp was in very good condition and though the vinyl had faded with time, it most probably would clean up OK. All the Mullard valves (tubes) were fine and were retained. The valve line-up is:- 1 x EF86, 1 x ECC83, 1 x EL84 and 1 x EZ80 rectifier. 

Oh, by the way........whilst the tremolo speed control is on the side with the other controls; the tremolo depth control was actually originally on the foot-switch itself! Quite an ingenious idea really to save having to step back to the amp to alter the depth! The original foot-switch was missing from this specimen unfortunately.

Quite a straightforward job really, and with a Fender Strat plugged into her she sounded awesome overdriven! A nice, simple, SE (single ended) amp................and another happy customer.

Cheers, John.
