anstec's picture

Ist there any one has got a replacement circuit for that dubious IC (LA2500) for the base current in the power AMP of the receiver ? The original IC cost 50 Pound, I am not crazy to pay that.
Has got anyone exerperience with that special power amp base current circuit ?
Is it really necassary ? I don't think so, may its possible to use an alternative circuit ?
