>> 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!
