TR-4 - V11 12BZ6

n4buq All Messages By This Member #84639 The serial number for my TR-4 is 26040 which is presumably a Version 3 rig. According to Garey's TR-4 documentation, V11 switched from a 12BA6 to a 12BZ6 at Version 4 (S/N 27000) but my TR-4's V11 is a 12BZ6 (not just the tube but the label beside its socket as well). Is it possible Garey's chart is incorrect or am I misunderstanding it? I found the following comment from Garey as well: /g/DRAKE-RADIO/message/13132 I'm just curious as to the apparent discrepancy. Anyone know? Thanks, Barry - N4BUQ
