I have a 12KP4A CRT that tests great and who I aquired it from tells me it is from a collection of nos crts he had for many years. This crt does not use an ion trap and is a direct replacement for the 12LP4 which uses an ion trap. I am willing to trade this CRT for a bright good working 7JP4 CRT not an oscilloscope tube but rather a b&w for TVs. Located in NY. Tim, 845-292-6251, timshawe at yahoo dot com (3/12/15)

Now available for sale: Replacement for the vertical dynamic
convergence transformer for the RCA CT100 color TV. Price $200. I
will pot the new transformer in your old transformer housing using
silicone rubber for an additional $40.
The vertical dynamic convergence transformer in the RCA CT100 color
TV is subject to a high failure rate for several reasons. First, the
transformer is would with very fine wire, (#40 and # 43 gauge). This
fine wire is subject to damage due to corrosion caused by acids and
impurities in the materials used to construct the transformer, and
from moisture intrusion into the pitch which was used to pot the
transformer. The pitch expands and contracts with temperature, and
develops cracks. In addition to moisture intrusion, the movement of
the pitch may lead to mechanical failure of the fine wires where
they are joined to the larger external lead wires. The failure modes
show up as open circuits on either the primary, or more frequently,
the secondary windings. While this will not cause any damage to the
TV, it will prevent proper convergence, and may lead to loss of
focus voltage at the CRT.
Second, is the 3-4KV DC focus voltage applied to the secondary of
the transformer. This makes the transformer prone to arcing or
shorting from secondary to primary. This can lead to a more
catastrophic failure. If a short develops from secondary to primary,
all the power from the focus
rectifier is dissipated into the focus potentiometer. And if the
wiper of the focus pot is near the high potential side, all the
power is dissipated in a small portion of the resistive element of
the potentiometer, burning it out in a matter of only a few seconds.
I have seen several convergence transformers which were open circuit
at the start of a CT100 restoration, and have witnessed two
transformers short out after the set was restored and powered up,
resulting in the destruction of one focus potentiometer. This is
what has inspired me to take on the challenge of having a
replacement transformer built. These transformers have been
several CT100 TVs, as well as Westinghouse, Silvertone and Sylvania
15" color TVs.
So you 15" color TV owners may want to consider one of these
replacement transformers. Supplies are limited, with no assurance of
Any questions email or call. I will bring several transformers to
the ETF convention. If you think you will buy one at the convention,
please let me know so I bring enough.

|Pete has a Brand New 5AP4 in a sealed box from approx. 1940's
and inquiring if any one is need of this CRT. He has sold
several of these tubes and all of the customers have been very happy
with the brightness and clear focus of these 5AP4s. They are
an excellent replacement for the 5BP4 and are much brighter.
