HICKOK Model 800A Dynamic Mutual Conductance Tube Tester For Sale

HICKOK Model 800A Dynamic Mutual Conductance Tube Tester

I have recently used the tester and it is ingood working condition. Roll chart is functional and legible. Known good and bad tubes were tested with satisfactory results.Unit calibrates to \"Line Voltage Adjust\" mark (and beyond) on meterwithout any problem (see picture 3). Unit is exceptionally clean. It was originally owned by a local Radio/TV store and I bought it from the owner\'s estate about 35+ years ago. It looks like it did not receive much use in the store and it has had only occasional, personaluse since then. See pictures.

Extras Included:

1.Original instruction manual (in excellent condition) which includes a complete 800A circuit diagram dated 11/24/65 and instructions for modifying the unit to operate on 230V AC if desired.

2.Acopy (in fairly good condition) of Hickok booklet: “Test Data for Model 800 & 800A Tube Testers”, which supplements the roll chart and includes data for obsolete and foreign tubes.

3.Includes plate/grid cap connector and a jumper wire (see picture 1).

Due to age andshipping the unit is sold AS IS. The unit is working now and I expect it will work when you receive it but I can make no guarantees. No Returns.
