Well I am to mentally challanged to insert 2 jpg's of the schematics.I need help,a friend gave me a 1950's era Talking Book record player.I has a Stomberg-Carlson Model AD "Talking Book"Amplifier in it.Its a single ended 12AX7 preamp,6X4 rect.,6CM6 power tube.It works,but the stock volume/tone circuit are setup wrong for a guitar/harp suite case amp.I have the orginal schematic and the one I did the proposed mods on.I need someone smarter than me to go over my mods and see if I am on the right track.My mods are based on the Kalamazoo#1,a very similar amp.Please E-mail me to get the 2 schematics abenecki@sbcglobal.net .Thanx,as always for the help and forgive my kraptastic spelling.

I think I maybe got it. Errrr, not quite.  Don't worry, I made 'em work for you.  The deal is, don't use the URL code provided by Photobucket, use their IMG code instead. Then, when you're typing your message on this forum, look up above the text entry box, and find the fourth icon from the left, in the lower row. Click on it, and you'll get this: [img] [/img] When you see that, simply type the Photobucket IMG code between the two tags. Even easier, just copy that code to your clipboard, then paste it between the two tags.  HTH sumgai |
