Hi All,
Before I will start to do fault diagnosis and try to find reson for it, it
would be nice to have few comments from you, more experinced with amps and
specially with AL-1500. The following indications has been made:
1. Power dificult to find, it gives less than 1 Kw output. Driven
Power has to be about 45 Watts. If it exceeds this level of driven power
the Amp. trips down the protection. Usualy it was necessary to have about 90
Watts to have about 1,5 Kw. Tunning was easy and not at all critical.
2. Grid current is very low, either in CW or Phone, both almost dont move
the
nedle and after aplying Driven Power Plate current goes high sky to 700Ma.
and in some bands almos 1 A.
3. The situation started by no reason. There was no noises, no sparks
and no smells, just went crazy !?
All the ideas and advice are very welcome!
