A 70 cabinet with a 20 chassis and dual 71A's? - OldRestorer - 11-04-2019
So I bought a phonograph yesterday and he had this there too. He said it was a 70 and it was all restored electronically. For $75.00 restored I took it since I dont actually own a 70. I ended up with a 70 cabinet, a 20 chassis, and dual 71A's?
Is this a 21?

It's 21. You lucky bastard you.
And it is not a 70 cabinet, as it has holes same as 21, that is 3 and not 4.

Another difference between the 20/21 and the 70 is the base of the cabinet. The baseboard on the 20/21 has three holes to secure the chassis and the 70 have four. Methinks Mike is referring to the knobs.

Cool...
The cabinet has a few issues on the arch but it is a good looking radio from the front.

It could be an early production 21 which still used the 20 chassis until Philco switched to the 21 chassis with dual 45 outputs.
HOWEVER
The knobs are not correct - early production 21 sets witrh 20 chassis still used 20 knobs. Later production 21 sets used rosettes, but a medium rosette for tuning and two small rosettes for off-on and volume. This one has a large rosette knob and two medium rosettes.
Pull the tuning knob off. If the front panel has a large hole (made for a 20 style tuning knob), then it is an early production 20. If it has a small hole, it is a later 21 cabinet into which someone has stuck a 20 chassis.

Well,
It is a large hole... The guy I bought it from put the knobs on. I'll throw on some 20 knobs..

It's a shame the grill cloth has that one hole in it. It is in great shape otherwise and seems original.
It almost merits trying to patch it rather than replace altogether.
A patch cut from some unusable piece of original cloth which could be found would do the job.

Ok so the early 21 had 20 knobs.. Which set?

The photo on the left is correct.
The photo on the right is an (incorrect) mix of a Model 20 tuning knob with later small rosette knobs.
