Probably. Every FL-2100B I've ever come across was a restoration project,
either in the past, or currently, or in the making. It's a knockoff of an
SB-200, but Heath did a better job.

HELP !! Started a restoration by accident, was using amp on 75meters when
I heard a ping and wattage dropped off to about 200 watts, I immediately
shutdown the amp and unplugged it. Upon investigation found the doorknob cap
between the tubes had a piece missing. The ping I heard was the broken
ceramic hitting the cooling fans. I decided to inspect all the other
doorknob caps and found 6 had cracks. I ordered and replace all doorknob
caps as well as the bleeder resistors. Amp works ok on 75 meters (about 400
out) but presents a high swr on every other band. Tried per band coil
alignment, but no joy. Opened the access panel to tuned inputs and found a
rf choke looks like it may have flash/arced. Am I right in my assumption
that I may have to replace mica caps and grid resistors as well as that
funky choke. Need some experienced guys because I am no genius when it
comes to electronics. Thanks in advance for any help you can offer. Jay
