calibrated Sencore TC28 Hybrider — best Mighty Mite — professional tube tester – $369 free ship
TC28 Hybrider is the King of the Mighty Mite series, with significantly better build quality and best test circuit of all Mighty Mite models. No comparison, really.
Includes original setup data book. As part of diligent servicing and calibration, I have checked (and replaced where needed) all load resistors, all new electrolytic capacitors, and calibrated this beautiful test instrument. New rubber feet installed on bottom. Grounded line cord installed.
The TC28 Mighty Mite is popular among technicians because: (1) complete solid-state design for extreme reliability, (2) full load cathode current test method with Life Test option, (3) ultra-sensitive 100-megohm leakage test, and (4) thorough shorts test due to a full compliment of lockout switches that prevent false shorts or miss real shorts. Made in USA.
Fantastic opportunity to buy a top quality test instrument, nice condition, professionally serviced and calibrated.

EICO 950B R-C professional Capacitor Tester $229 free ship USA
We went ~overboard! to rebuild & calibrate this Professional
Eico Capacitor Tester, one of the BEST cap testers available!
Made in the USA
“the best” Working Condition,
Easy-to-Use MAGIC EYE TUBE operation.
If you are the type of person who BUYS THE BEST and is willing to pay a higher price for that degree of excellence, then this Cap Tester is what you want.
Why? Well, we went “overboard” in rebuilding this unit!
The following features are above-and-beyond a stock rebuild, suitable for people who WANT THE BEST. If you are simply a price-shopper looking for a cheap tester, then this is not for you.
- High precision (1% or better) reference capacitors installed, verified with Fluke meter
- Line fuse installed internally
- computer grade 3-wire grounded line cord installed
- magic eye tube installed with excellent brightness
- brand-new alligator test leads included (all have soldered-connections, no junk)
- brand-new rubber feet on bottom
No junk here…only the best. This capacitor tester has been professionally repaired and calibrated by us, and with the added extra precision calibration and additional features as described above. Works awesome, looks fabulous. Just what you need to help repair those jukebox amps and other tube amps, antique radios, etc.
This is a vintage American-made Eico Capacitor tester. This is a true “load” tester, and can put up to 500 Volts to the capacitor under test for a true load leakage test. This photo shows the power of this unit, showing the load voltage at max setting as read by my Fluke voltmeter. (Fluke meter is not part of this sale and is shown to demonstrate unit functionality).
This is the BEST type of test for any capacitor because it uses realistic voltages that the capacitor must be able to handle. Usage is rather common-sense — this is an out-of-circuit capacitor tester, not an in-circuit tester. I have an article discussing usage here on my website, and a copy of usage instructions will be provided.
Since this tester outputs high voltages, do not buy this type of test equipment if you lack the repair skills to use it properly.

This is a Premium Quality, professionally repaired and calibrated cap tester, and is very useful for anyone repairing vintage tube equipment, such as Tube Amps, old jukeboxes, antique radios, etc. Top Quality here!
