    Italian linear?

    Thank you and all the others on here for keeping the hobby alive - if it is not enjoyed and shared it will die.

    Italian linear?

    Do they not test the units before they ship them to see if the parts they put in them are up to specification. I got one of the newer models with the MS1051 and it kills the receive when either transmit or receive is switched on. I tried searching for the MS1051 Transistor is what got me on this...

    They are still selling the KL-200P on NEWEGG for $75.00 and Free Shipping.

    RM KL203-P

    If you lower your mic gain it will also lower your output power - or it does if using an old D-104 Power mic and gets rid of background distortion.

    President AR144 no tx rx

    If I am not mistaken it is the same as the ax144 which there is information for.

    Rm Italy KL-503 watts vs amps

    Are they doing the same thing with the newer 200P with the MS1051?

    Italian linear?

    I like the 200 amps there is less parts to fail and simpler to find the problem - I gave one of the 203 amps to a friend that I got off E-bay for $25.00 and Free Shipping and there was nothing wrong with it and it works great with no problem at all it did not have the pre-amp which is mainly...

    It would be hard to build one yourself for what they sell for - NEWEGG sells them all the time for less than $65.00 with FREE Shipping and they are nice fused units I really like the quality for the price not just a copper-clad board with parts soldered everywhere very well made.

    I have even had power supplies fail and over-volt them - the output power goes wild,but still has not damaged them. The 200's are really simple very few parts with a simple circuit makes repair fairly easy. You have one bf199 transistor on the pre-amp that will fail and the relays have issues...

    Italian linear?

    I have 4 of the RM Italy KL-200P Amps and one is over 20 years old and they all have the single SD1446 final in them. In over 20 years I have never blown a final - I have replaced the BF199 receive transistor from Lightning Strikes too close and the relays have failed but that is just minor...

    Do you have a link to Nomad's Article on the Pre-amp problem?

    Rm Italy KL-503 watts vs amps

    What are common problems with the KL200P Amps when the receive dies when the amp is switched on.
