Get a lot of old PA and group amplifiers in. Some, like this one have been round the block a few times. This is a Spanish built amp. probably going back to the late 70s early 80s. Straight forward set up, well made and easy to access. main fault was one shorted output transistor. No other damage done as a result. Being a budget repair, owner was not too bothered about some tired capacitors. Will see it again soon no doubt. These things go on and on, probably helped by a fan big enough to make it hover.
