T-160-L

[W2NBC]

Hey folks,

Was rummaging through my "stash" of tubes. It always pays to open those unidentified boxes.. I found 8 marked NOS Cetron T-160-L's wrapped in 70's dated newspaper.. Time to build another modulator!

Here's the question.. When did the Cetron T-160-L's change shape (and name)  from ST to coke bottle , 572B's??

Dunno but yours is radiating a digital halo artifact as shown on the table.

IIRC the original introduction of those is in '68 QST.

I upgraded from 811As to 572B\T160L around '72 I think I paid around $16

Taylor developed the T-160L tube as an AM modulator and soon merged with Continental Electronics who then got into the power grid business and changed the name to Cetron. Since volume sales for AM was dead by then they sold the idea of a cheap SSB amp tube to Heathkit to replace the wimpy 811A.

United Electronics produced the round top, thats not an ST BTW, under its own name and also private labeled for others such as Cetron and Waters. Waters was a reseller and Cetron likely didnt have enough production capacity to keep up with Heath at first.
I have the UE, Waters and Cetron versions here. Cetron also private labled the shoulder design for Raytheon, GE, Philips, O'Malley, and possible others.

The tube business was a tangled web for sure.
