Comparison with 067-0502-01

TekWiki asks the question: What is the difference? I have both units and have done an extensive review. Looking at the front panels [TNX 4 pix] of the –00 & the –01, it seems that the –01 dropped the × 100 Amplifier section. The front panel is re-laid out, but what remains seems to be identical to the corresponding sections from the –00. In other words, the –00 provides a superset of the functionality of the -01. Note that the –00 transformer [T310] has 6 windings and the –01 transformer [also T310] has 5 windings. Some currents are different, as indicated. I have made my own notes for the project of working on the two. Using the schematics for organization, I arrived at the following table. I am using a re-organization of the sheets, the block diagram of the –00 and this table:
Section -00 -01 Sheet in -00 Sheet in -01 Sheet in proposed consolidated drawing set
Square Wave calibrator Used in both Used in both 1 1 [s/b 1]
× 100 Amplifier Used in -00 Deleted in -01 2 -- [s/b 2]
Power Supply -00 has more sections Than –01 3 2 [s/b 3A for -00 & 3B for -01]
T310 P/N 120-0442-00 P/N 120-0615-00 3 2 3A/3B
High voltage, B+ 285 VRMS, 35 mA 300 VDC, 225 VDC & 100 VDC 125 VRMS, 2 mA 100 VDC only 3 2 3A/3B
6.3 VAC (Chopper) Used in -00 Used in -01, noted as 1.84 A 3 2 3A/3B
100 VRMS (-100 VDC) Used in -00, 40 mA Used in -01, 31 mA 3 2 3A/3B
6.3 VAC (MV 6DJ8) Used in -00 Used in -01 3 2 3A/3B
330 VRMS (Floating Supply) Used in -00 Used in -01 3 2 3A/3B
20 VRMS (× 100 Filaments) Used in -00 Not used in –01 T310 3 2 3A/3B
Floating power supply Used in both; drives Square Wave MV Used in both; drives Square Wave MV 4 3 [s/b 4]
