RCA 816 Mercury Vapor Rectifier Advert

The 816 is the Junior of the 866/866A.
Might need to procure a few of these as well.

RCA Sound Translation....... next to perfect!

The LC-1A is on the list of "full range" speakers I'd like to owen. Their price keeps going up and I've missed local bargains twice now.... Sigh.

1938 RCA Transmitting Tubes Technical Manual

Here is some tube porn for the evening. My friend Chris dropped this 1938 RCA manual by today. It is amazing and the tube diagrams are beautiful. It is a little fragile so I didn't flatten the pages to get the images.

45 145 245 345 445 Tubes

My friend the TubeHoarder found a big box of 45 tubes for me to try in my amp. Not sure of the condition but I don't often get to roll through a dozen gobes and then a dozen coke bottles.
 
Engraved base de Forest Audio 445... Beautiful.

 Engraved base Arcturus Power Amplifier 145.


 Engraved base Cunningham CX 345. 
A good pic on this one.

 Engraved base ECHOTRON. Great name. 
It is strange that the filament is resting on the grid in this one. 

 It was really difficult to get a pic of the Majestic engraved base.

 Haven't found any info on this engraved base Marvin MX 245.

 Another Engraved Base RCA Radiotron 45

 Another RCA Radiotron UX 245 Engraved Base

National Union Coke Bottles with engraved  base. Very cool.

Out of the engraved bases now. Here is a selection of RCA coke bottle 45s.

Do vintage tubes sound better than modern? I don't know for sure.
Which do you prefer?
I get a kick out of running antique tubes. There is something special about listening to music through  old triodes. Listening to history. It doesn't hurt that the tubes look beautiful as well.

Very Early Pro Sound - Field Coils with Horns and Triodes 245 250

This is one of my favorite early ads because it has it all like field coils, horns, triodes in the flavor of 250 and 245.

$20 in 1930 equals about $275 today.
 Nice selection of field coils from the early guys Jensen and Utah.
 I want everything I build to look like these early pro amps.

1940's RCA TWIN POWER

 RCA Twin Power or the 3ft cube. I love big speakers but I still have to wonder why they designed and built a 3ft cube speaker. Love to hear this one.
