RM/KL300 big problem!!
I have the above mentioned burner,but it needs rebuilding with all new parts (i think).
Does anybody know the cost of a rebuild?
Its a 24 volt amp for my mobile station,im lost without it,as my rig only puts out 25 watts,the Yanks cant hear me!!
I bought is for spares/repairs but it is unsafe as both wires are soldered together,its not earthed to chassis,and appears to have burn marks.
Is it worth repairing,are the parts cheap to replace??
Cheers,Craig.

Re: RM/KL300 big problem!!
The RM 300 (24 volt) uses a single MRF422 AS THE RF power transitor, these can be pricey. depending on if its blown or not, and how much you could find a cheap MRF422, it may not be worth fixing.
have a look on the RM website all plans and info for all there amps is on there.

Re: RM/KL300 big problem!!
hi there craig. i can tell you that the mrf422 is £40+!!! and thats if you can find any in the uk now as there like rocking horse poo!! also why would somebody solder the wires together? who knows whats happend to that poor amp! might be better of just keeping it as spares ie cases and swithes and what ever else you can save! and getting a new one! does it have to be 24 volt? if not a new kl400/500 would see you good. 73s.
