Hi Don (VE1BN)and others,
My Paragon is fixed!
I recieved new toroids yesterday (free of charge from TT, what a great
company!!) and today replaced the output toroid and the ferrite in the 12
Volt line. I now have full output on all bands again :)
I am not sure now which one of the two ferrites was causing the trouble, but
I am pritty sure that it was the 12 V line one. I can imagine that the
higher the frequncy gets, the more losses will occur if the ferrite lost its
permeability due excessive heat as happened in my case when capacitor C25
went bad.
So go for changing the ferrite in the 12 V line to start with Don!
Thanks, as by exhanging the info in this net, we found the problem!
73, Dick/PA2DWH

Hello Dick -
Guess it is too early for you to have received the toroid coils from
Ten-Tec for your Paragon.
If you did order them, are they able to send you replacements?
I am just curious, (hope I am not being a bother.)
I have received the matched pair of MRF458 finals, and the two
drivers ordered. If replacing these does not solve the HF-end
low output power problem then I may also have to order an output
toroid coil.
Am very interested in any improvements you get, Dick.
Again, 73 -
