A rare find - in the back of an old furniture store!!
I have a Rogers/Majestic CANADIAN set, model R371. It has three tubes - a 6A7S, 6F7S, and an 89RS.It runs on 110 V AC, 25 - 60 Hz.
The 6A7 and 6F7 are common tubes , except for the Rogers types which have spray - on shields!! ( Rogers started his own line of tubes in the 1930s with spray on shields which dispensed with the need for real metal shields. Quite an innovation at the time.
Would it be ok to subtitute a "conventional" ( US made ) 6A7 and 6F7, using a metal shield if necessary?
Also, I have NO US equivalent to the 89RS tube. This looks like a combination audio output and full wave rectifier, all in one envelope. Anyone have any ideas?
On another note - perhaps this is not the proper forum for this but:
Yours truly just got laid off from his Microwave Engineering job( of 31 years ). Does anyone know of any positions in the local (Marlborough, Mass) area?
Thanks Again
Lou

Lou,
I've got two of these sets and the only place I've found the 89RS tube is at Grandpa's Radio Shop - George Found 519-576-2570 in Kitchener, Ontario, Canada.
As far as trading out the other two, there are several websites that have Rogers Tube Substitution Guides.

PS I forgot to mention that one set has Rogers on the dial and the other has Majestic.
89RS is listed in Tube Lore as being same as 6G7, which I've never seen (rectifier-pentode). You could use standard tubes with shields added. One difference shields need to be grounded to chassis. Spray shields were connected to cathode of a tube. There wasn't enough pins to use chassis ground.
Any guys from DEC left in Marlborough? Twenty years ago I would have had contacts for possible jobs.
