HEATHKIT OL-1 OSCILLOSCOPE For your consideration. We are offering a vintage o-scope. From the estate of a local TV repairman. Used. Found to be working, with a weak display.

You are bidding on an immaculate Tektronix 310A oscilloscope in working condition with original manual and custom-made aluminum case. Tektronix has been one of the two or three premier manufacturers of oscilloscopes since 1946. The other contenders are Dumont and Hewlett-Packard) This auction is for one of the company's nicest vintage vacuum tube scopes ever made. The model 310A. The 310 was the worlds first really good portable scope. It was a direct response to IBM's desire for a high quality portable scope that could be used to service their computers in the field. IBM collaborated with Tek in designing the 310, and some early 310's even bear the IBM logo. Introduced in 1959. The 310A was an improved version of the 310, with better construction and silicon diode rectifiers. It enjoyed an extremely long production run through ... morethe 1960's, with the last 310A being manufactured in 1971. The 310A is built like a tank(see photos) and has a clever hinged chassis that unfolds the scope like a book for easy service. It uses 34 vacuum tubes to achieve what was in the 1960's state-of-the-art sensitivity and linearity up to its 4MHz bandwidth. Even today a 310A is more than adequate for audio. Analog television, radio, and vintage computer servicing. This particular 310A is serial number 022106. It is in near-mint cosmetic condition(see photos) With all the original hardware including the little spool of silver solder on the back panel(photo 3) I have never seen a cleaner vintage Tek scope of any kind. This scope is working. The first and last photos show the scope free-running with the audio stream of Gershwin's Rhapsody in Blue as input. More interesting from a technical standpoint is photo 6. Which shows the scope displaying the square wave output of the built-in calibrator. Comparison of the trace with the settings of the knobs shows that the gain and sweep are almost perfect. Given the age of this scope, however, it would be worth checking the calibration if you plan to use it for precision me
