[MRCA] Cleaning off a shelf - PP-621/URR

[Roger Klingman]

Question, What does a PP-621/URR, made by Motorola for Collins, uses a pair of 26Z5Ws go with?
At insistance of the xyl, these are yours for my cost plus shipping:
1. CM-14/URR, the Comparator used in AN/URA-6, -7 and -8.  It is missing the front filter (which looks like a speaker cover). On that cover would have been the RCA symbol and "115v 50-60~" in addition to the nameplate. This is definitely USN RTTY. Interior looks pristine.
2. RM-25-A Air Ministry, 1943 
3. AM-103 B/U by Boehme, Inc. 1952 + manual; it is an a f amplifier used with teletype. Tube content- 1 6SJ7, 1 6H6, 2 6SN7GT, 2 6V6, 3 5Y3GT - untested.
My costs:
1. $10
2. $5
3. $25
73,
Roger
