VE7AVV – YAESU FL-2100Z Amplifier Repairs
Article rights to VE7AVV
The FL-2100Z amplifier referenced in the following images is the 6-Band model covering 10m thru 160m (no WARC bands) and not the 9-Band version that included the WARC bands. I believe YAESU called this an off-shore or export model of the amplifier — but it is definitely a FL-2100Z.

Here is where I believe the (band switch) trouble began….
Use a mirror to examine these parts closely so you can view the bottoms and then replace these weak links with parts from http://www.vcnet.com/measures/ . Install all the parts in the 572B kit.

The stock parasitic suppression proved to be a very weak link in the overall design of this amplifier

I am indebted to John, VE7ML; Dale, VE7SV; and Chuck, VE7WO for their invaluable assistance in making repairs to this amplifier — without them, this amp would likely have become scrap metal.
Thanks but not much to report sadly..My amp had input-output problems, a little circuit board burnt to a frazzle…G.
Hi,
I am looking for a bandswich ( 9 positions ) for a Yaesu FL2100Z amplifier. Do you have any idea where I can find such a switch? Any input would be highly appreciated.

Dear Fellow Hams, We are in the process to restore the BPF board at the back of this linear.
Where do I find parts or alternative information on the values of the torroids and caps??
Any information or assistance will be welcome.
Thank you in anticipation,
