A Wobbluscope is an instrument that combines a sweep generator, a marker generator, and an oscilloscope. It is a very useful unit for the alignment of RF and IF video sections of a TV receiver. It may not have all the features of a high quality sweep generator but it is an economical and compact piece of equipment specially designed for TV servicing. The oscilloscope usually has a provision for TV-V(vertical) and TV-H(horizontal) sweep modes. An RF output, down to MHz, is available for video amplifier testing.
While we have found little information thus far regarding any items sold under the trade-name, 'Wobbluscope' (capitalized), Philco's model 7008 Visual Alignment Generator (circa 1950) is one example of the 'wobbluscope' (generic term, uncapitalized) instrument as described by H S KALSI in the preceding paragraph. We have restored examples of both the Philco model 7008 wobbluscope instrument and the related Tel-Instrument Co. model 1200A Wobbulator in our shop's Vintage Test Equipment collection, both of which we use regularly in our Vintage TV Restoration shop. We will include a photo of our Philco model 7008 to accompany this article at a later date.
