Lab Setup Circa 2007


Pictures of my Lab Bench and Equipment, sort of a mess, but I was working on a project. I'm setup for audio vacuum tube amplifier work and antique radio repair. I have also put together a GPIB system to automate measurement of plate characteristics.

Marconi FT 2005 R

Hello. Nice bench set up with a lot of room. I am currently using my dining room table. lol I collect and use lots of vintage audio equipment. In particular reel to reel tape decks. I have amassed some test equipment for my alignment process. I recently got a very good condition and it works Marconi dual tone generator. I am out looking for a users manual and such. I could stumble through and figure out how to use it for my purposes but would like to get a manual. Do you have a manual for this? Can you give me some sources to find the manual? Your help would be greatly appreciated. George Thomas


Hi George,

I don't have the manual. The closest I've found is the spec sheet found at

The generator is pretty simple to use, if you have specific questions, maybe I can help. Cheers, Imre
