I have gotten a nice shape Bogen J130 PA amp.I need a schematic for it.Its not one of the more common Bogens.I think its a late 1940's-early 1950's era,by the design and tube type.Tubes are as follows:1-5UFG rect.,2-6L6G Coke Bottle type,2-Black metal 6FS5,1-6SL7G.1 mic input on side with 1-phono"RCA type"Back panel has David Bogen Co.,Inc.,New York 14,NY.Top on back marked David Bogen J130 or JI30 Series F-76.Any info,leeds,comments or help always welcome.
 
Found out simalar to 53 wide bassman

After looking the ciircuit over and drawing my own schematic.This Bogen J130 is Very simalar to a Fender widebase Bassman.It even shares the same paraphased 6SL7GT phase inverter setup.The tone stack is setup a wee bit different,and 2 6FS5 instead of 6SC7.Overall a good place to start.Thanx all.
