Standel schematics?
Anyone have a source for a schematic for a Standel 25L15? It's an oddball, with 807 output tubes. Thanks in advance for the help.  
Randy.

Randy,  
 
If you're using 807s the amp should be old enough to easily trace the wiring. The 807 was one of the first beam power tubes and is essentially a higher voltage 6L6 variant widely used for RF work. After WWII there was a glut of war surplus 807s on the market and they enjoyed a heyday as audio output tubes - roughly 46-53, or so until the 5881 was introduced by Tungsol in 1950 became a standard. Good 807s are still available quite cheap and this sounds like a good restoration project.

Just a question that came to mind when I saw the title...  
 
Does anyone remember and know model numbers or names to a solid state standel series that was issued in the late 60's?  
 
Each part of the series was considered "modular" and was (this is memory) about 24" wide, 16-18" tall, maybe 12-14" deep, and maybe two or three modules could be mounted on a stand... the intent being to rotate the module for proper sound projection.  
 
Essentially three module types... an extention speaker type, a powered extention speaker type, and a "control" module... with speaker and amp... essentially a combo.  
 
They used dual concentric controls. The grille was like extruded metal, and the speakers were port/folded horn loaded, with slots on both sides of the cabinet.  
 
And I believe rumor was that the electronics were potted... since everyone knows solid state lasts forever.  
 
I want to get a schematic for the control module of the series... but I don't know what to ask for.  
 
Thanks for any help.

Most of us were potted in the late sixties, but we all didn't last forever...

Anyway, Standell's homepage goes into the history, a bit. They might could help.
