[Amps] FL2OOOB

[Mike Schatzberg]

Hello Morrie:

The first thing to try is to lengthen the coax between the amp and the
transceiver.

I would recommend that the cable be at least 20 feet in length, RG 8 type
coax.  Then, go ahead and retune the input coils and see if the SWR can be
greatly improved.

This amp was designed to be driven by tube exciters, and this change may
well help with transistor output exciters.

Regards,

> Hi A friend has just purchased a FL2000B with Cetron 572b installed .His
problem is that he cannot get the swr down to a reasonable level  with the
tuning slugs .Has someone else had this problem if so what is the cure also
what is the drive impedance. Tnx Morrie
