ANSWER: NO, I never obtained any manuals for any of the oscilloscopes below. However, if schematics are available then they will be posted below. Please check other websites that sell equipment manuals or SAMS Photofacts for schematics.

Heathkit information, including many oscilloscope schematics, can be found here: http://www.heathkit-museum.com/hvmtest.shtml

This is a great tube oscilloscope made in the late 1950's or 60's and has a 5" CRT. The schematic is available for download here: bh34schematic.pdf (473KB).

A solid state oscilloscope with a 5" CRT that probably came as a kit.

This professional version of the generic HeathKit tube oscilloscope is pretty simple, consisting of a 5" CRT and 500KHz sweep.

This is a 40s to 50s Heathkit HO-10 "Monitor-Scope," which was used as a station monitor. Basically it was for monitoring transmissions especially from a ham station. However, this device is actually an unusual oscilloscope with a 3" CRT and a compact chassis.

A simple general purpose HeathKit tube oscilloscope with a 5" CRT and 150KHz sweep.

This is a nifty portable tube oscilloscope manufactured by Hickok for the Navy. This oscilloscope is a pain to repair because it was crammed with nine miniature tubes and a 3-inch 3RP1 CRT.

This Lambda is a quite small oscilloscope from around the 1940s made by Lambda Electronics Corporation in NYC. This oscilloscope is one of the most primitive and lacks input amplifiers. The oscilloscope only consists of one rectifer tube and the CRT! It was most likely used as a basic station monitor because the screen filter has "Carrier" labeled on it.

This is a very small 1940s Philco Junior 7019 oscilloscope with 3 tubes and a 2-inch 2AP1 CRT. This oscilloscope is identical to the Waterman "Pocket-Scope" shown at the end of this page, but painted in blue. The circutry is identical to that in the Waterman, so if a schematic is needed then refer to the Waterman schematic at the bottom of this page.

This is a very old oscilloscope from around the thirties by Supreme Instruments Corportation and has a three-inch 3AP1 CRT.

This Tektronix oscilloscope is one of the finest pieces of test equipment from the early 1970s. It has a nice 4" by 3.5" CRT screen and a whopping 200MHz sweep. I use this oscilloscope frequently on my workbench.

This 1946 WaterMan oscilloscope is called a "Pocket-Scope" because of its small size. It consists of 3 tubes and a 2-inch 2AP1 CRT. The oscilloscope was recapped and works fairly well for a 3 tuber. These oscilloscopes were probably intended for laboratory demonstrations and not for actual field use. This oscilloscope has a measly 50KHz sweep, but that was with just one 6J6 sweep tube! The dimensions of this oscilloscope are roughly 4" x 6" x 10". The model on mine says 0510A, but the circuitry is identical to that of a S-10A so the schematic is available here for download: waterman.pdf (408KB).
