Coming around toward the end of a full electronic restoration on this 1950 Admiral Model 22X26, featuring the 12″ 20Z1 chassis.


Contrasting the technology with a selection from my Star Trek TNG VHS cassette library.

Full capacitor compliment, resistors replaced where necessary, I.F. and sweep alignment performed. Original CRT is in great condition!

Just posting a quick update on the status of Rich from New Zealand’s Zenith Porthole restoration.

Power supply block has been cleaned up and rebuilt. All capacitors replaced, both of the corroded high wattage sand covered resistors in the audio section and one small charred 1/2 watt resistor.

The main chassis is undergoing complete rebuild. Everything is going well except for a bad volume control/power switch assembly. No direct replacements are available at this time so we might have to improvise this a tad!


The Predicta from Heck, Pt. 2

Following up from the earlier post, covering initial inspection and dismantling of this set.

The cabinet has just returned from Lance at Nook and Cranny Refinishing… and what a beautiful job! The cabinet has been restored using real veneer on the top and sides, as well as burlwood veneer on the front, which has also been hand pinstriped. All brass has been buffed out as well. Legs are slightly bent and need some help… but I will work on this later.

The electronics are currently in progress; I will be posting an update on this soon!

Zenith Porthole “The Aldrich” pt.2

Following up on the progress on the 1951 Zenith Porthole sent in by Rich in New Zealand, check out the arrival and unpackaging if you haven’t already!

Part 1

Had a chance to pull the chassis and have a look today. Everything’s very clean and complete, and we had already determined last time that the CRT is going to be useable. Looks like the TV was home to a mouse at one time judging by all the debris found after removing the chassis… fortunately, none of the wiring is chewed through as I’ve seen with other such “fluff and circumstance.”

Very clean! Chassis does not appear to have had any repair or modifications save the large yellow dry electrolytic hanging underneath: left and center.

Original sticker off of the CRT will be re-adhered once everything is cleaned and back together.

57 Predicta Barberpole Resto – Initial Inspection


We just received this very complete 57 Philco Predicta Barberpole for repair. While the customer lives in Las Vegas; he purchased the TV from a seller nearby us in Walnut Creek so it was easy to arrange delivery.

These are the initial pictures- overall cosmetic and working condition. Just some notes: the screen cover is beginning to decompose as many of them do. This will require a buff and wax. The finish on the front portion of the cabinet is flaking off in many areas and drastically negates the visual appeal. The faux woodgrain on the back cover is in excellent condition… very good as this is hard to reproduce. White painted area has yellowed and has sustained damage on top near the neck. Electronically, the chassis starts up. Someone did some major repair work in 1995; even signed and dated the chassis. Unfortunately, many of the capacitors used in the repairs were NOS which are as bad or worse than the originals. Brown knobs on front are from a Holiday model Predicta and are mismatched. The correct knobs are white with no lettering. Suffers a vertical deflection malady resulting in a white line across the screen. Beam appears unfocused but it blurred by powdery residue on the inside of the screen cover; the CRT appears to be in good useable shape. A great starter for restoration!
