I've recently obtained some Horizontal Output (EHT or Flyback) transformers to suit HMV E1, E2, F1, F2, F3, F4 and F5 chassis. There are one each of 3 types. One of these also suits some 90 degree Healing and GE models.

They are NOS Rola, i.e. original fitment (Except for the E's where they are the HMV factory mod for the short-life British ones.) They are in original boxes and look like they were just made.

Anyone got a TV out of commission for want of one of these? I bought them because I might need one.....

Hi Ian, I'm looking for a Horizontal Output (EHT) transformer for my three 701 series Healing sets, one has a replacement RADAR/Rola transformer in it and looks almost like new, part number possibley 059, 058, 069 or 068? The other two set's transformers are rather old looking and looking like at the end of their life as are cracking up. I'll email you a few photo's if possible. I thought you may have some or know of where I might still be able to fine NOS examples. Regards, Barry.

Just as a matter of interest I have found that these Healing models had very reliable FBT’s.

Hi JJ

Yes, normally, but as I emailed to Barry, since his Healing 700 TVs had Radar TV replacements transformers in place of the original Rolas....

No the transformers I have are 70 and 90 degree types, i.e. much older. The 700 is 110 degree. So unlikely to work properly for you short of extensive modification.

One thing to watch with those sets - the adjustment of R619, if made incorrectly, will kill the transformer with time.
What used to happen is C618 would go S/C, reducing the width. Whereupon a lazy or ignorant "technician" would turn up R619 to increase the width, without regard for the B+Boost voltage, which should be 520 volts across C619 MAXIMUM. This critical requirement was never well documented.

If you don't wish to pull the transformer from the chassis, you could mask off the area, use a hair dryer, then soak the cracked transformer insulation with a spraycan of lacquer. Make sure the type you use is turps cleanup, not water based!

This issue of the horizontal "Stab" control maladjustment (and horizontal S correction) was widely misunderstood by service "techs" of the day who simply didn't understand its purpose, how it worked or the importance of setting it correctly.

Thanks Ian for your advice and assistance, I'm busy painting the eaves of my house at the moment among other things. I will attend to my 700 series Healings once I have more time. With the advice you have already provided I'm sure I'll get them up and going; I'll let you know how I go. You wealth of experience and knowledge is most welcome. Many thanks, Baz.
