Anyone who dismantles a -2100Z simply ain't right.
Far better to scrap out a -2100B...

The poor old 2100 series of amplifiers were pretty shoddy and messy in construction however in their heyday were probably all that a lot of hams could afford....Down here in VK a good 2100Z or B still bring $600-$800....However there should be a caveat on those old amplifiers as after 25-30 years of abuse the components are usually pretty near their last breath...I try to pick them up as cheaply as possible, "wreckers", because there are few useful components that can be salvaged....The power transformer is surprisingly robust though and I find that they are an excellent match for the small Russian GI-7B triodes and that makes for a good 6-800 watt pep output amplifier....Getting good RF components is difficult in VK....I have to import most of my parts from Europe and USA...However postage is the real bummer....I recently had a Peter Dahl Hypersil transformer custom built to my specifications by Harbach in the US....The transformer was only US $450...The unit weighs 48 pounds and packed 52 pounds....Priority airmail to VK was US275 even with customer discount....Ouch....However the quality of the Dahl transformers is excellent...Originally Posted by N8YX
Most of the transmitting tubes I buy these days are new, ex Russian military surplus from the cold war days....I only work with the triodes....Prices from my source in Ukraine are $15 for the GI-&BT tubes and $100 for the big GS-35B tubes....These tubes are old and must be conditioned before one puts them to work....I built a special simple power supply using a microwave transformer and variac so that I can increase HT on these tubes gradually while burning the filaments over a 48 hour period....To date I have had no failures....Russian military components are excellent quality..I use their HV doorknob capacitors and vacuum variable caps extensively as well as the triode tubes...
Rambling again....Put that down to senility....

Hello.
Here in Texas I come across a lot of CB modded "hamster" rigs, or Super CB as they call them.
The FT-101 is quite common but even Collins comes around.
And, yes, this stuff has been beaten, as in I frequently use a ball peen hammer to correct dents.
Repainting is the norm, with Blue as the pretty much standard color choice for me.
And, why blue? it is a very non threatening color.
I make little effort to restore such a radio, making it work correctly is far more important.
