Views of the model 21 as found. It was missing two knobs, two
71A tubes, one 80 rectifier tube and cabinet trim pieces. Photos
of the finished restoration will be posted here upon completion.
The chassis is marked model 20A (25Hz version) as the early
model 21's used the same chassis as the model 20.
The chassis was very rusty on top but the underside was
surprisingly clean. I completed the electrical restoration some
time back, the biggest issue being an open-circuit RF coil. I
replaced that from another junker model 20 chassis. Note the
RF tube screen is present and just visible in the photo third from
top on the right. The speaker cleaned up nicely. The gash in the
cone was repaired using rubber cement.

This chassis has an oversized power transformer and filter
condenser block in support of 25Hz operation. It works just fine
on 60Hz.

March 2015: cabinet being restored. I hope to have this soon!

Back in the spring of 2010, because of a busy schedule, I sent the partially restored cabinet for this
radio out to have its restoration completed. It needed a repro front-panel and base moulding installed
(all of which I supplied), the veneer patching on the arch, and re-finishing. After numerous assurances
from the restorer that it was almost complete and ready to be returned to me, as of 2016 I'm still waiting
for it. I'm wondering, will he ever make good on his numerous promises? Or did he in fact lose the set?
I restored the chassis years ago, not long after I purchased it. I would have given up on it long ago,
were it not for the fact that this is a rare variant of the model 21.
