Electrohome tubes

Philips was actually in Leaside during the time when these tubes were made. Only later after it closed the plant did it open in scarborough and this would have been early 70s.

Those of you around my vintage would have remembered the neon sign facing east south of Eglinton.

One of our family friends, an electronics guy actually worked there at the factory.

BTW I have some 12ax7s electrohome and they are VG. Built on the same plate structure as the amperex and they do have the amperex flash as well.

Actually it was Philips that bought and merged with Rogers tubes after 1946 in Canada and Electrohome that sourced from Philips/Rogers.

Many quite good, as their primary source was Philips - my father's console stereo came with stock Rogers branded Holland made EL34's - two quads. Philips had a factory in Scarborough. Electrohome also generally sourced Philips.

If you check into it you'll find out that Rogers manufactured tubes for many years before it was bought by Philips in 1946. The Roger's tubes works manufactured and developed many new tubes:

Edward Samuel (Tyne naming Samuels) Rogers founded the Rogers Radio Company, Ltd. of Toronto in 1924 - at the age of 24. Tyne page 349: "While on a trip to the United States in that same year, Rogers visited an American laboratory where he saw a small tube designed to be operated from ordinary household alternating currtent. When he went back to Toronto he took with him the Canadian patent rights to this tube."

It was Frederick S. McCullough who made this AC tube but it produced excessive hum. Rogers developped a better insulator for the heater and redesigned the heater to get lesser hum and produced this tube on August 26, 1925. Then he founded the Standard Radio Manufacturing Corporation in 1925 to manufacture radios using his AC-tubes called Type 32 - actually R32 and later also R30.

In 1928 Rogers was concentrating on the manufacture of tubes and he changed the name of his company to Rogers Radio Tube Company, Ltd. Later this company became the Rogers-Majestic Corporation. Rogers-Majestic was taken over by Philips in 1946 but Philips kept the Rogers-Majestic label.

They did rebrand before and after the Philips buy out but then so did everyone else. ;^)

I have some lovely Rogers labeled Mullard 7189s.
