Cossor 1099 and 1322 wobbulator
Hi folks, new member here. I've had this Cossor 1099 Oscillograph for a few years, but its specification is so poor that I wondered what old-time engineers managed to do with it ? So after repairing it I bought a Cossor Telecheck 1322 to put it through its paces.
With my "new" Telecheck much cleaning-away of 50 years of dirt and tobacco tar has been recently done, re-capping and testing about to be done, then power it up. Thanks to DavidW for a 1322 manual, and I have made myself a reference book (see photo). My main purpose is to study how wobbulators are made and used. There is a fascinating article that I found in Archive.org about the Cossor 343 which is very detailed and gives references for further reading. Beaky |

Scopes like the 1099 were to help with diagnosis of timebase faults and maybe a bit of Audio stuff.
They were also useful to set up FM IF stages with a wobulator. 100MHz scopes are the norm now but back in the day just being able to see what was going on in the timebase must have been helpful if not one of the "stock" faults. I have a few versions of various Cossor Sig Gens and Scopes I will eventually get around to putting them all on my web site Cheers Mike T
