1968 HMV 2662 BRC 1400 Series Chassis
I'm posting this on behalf of Gary (405 Fan)
Hi Gary here,
Today I popped over to see Chris and pick up my 24" HMV 2662 dual standard tv which I won on e-bay back in November. Graeme (valveboke) kindly transported it up north.
I have a soft spot for this particular model as it's the the same as the one my grandma rented from Rumbellows years ago. This set had not been used for about 10 years so I thought it best to check inside first. It doesn't seem to have had a soldering iron on in it's life. It still has the original dropper and tripler fitted. The only non Mazda valve fitted is a Mullard PCL805. Also the original Mazda gold star tube is there.
When powered up a narrow picture appeared. Looking at the circuit diagram I thought it must be a resistor in the width circuit. On checking R141 it read 10meg when it should be 3-3meg . Replacing it restored the width to normal. As you can see it has a good tube but the only downside is the state of the cabinet, Its badly scratched. I think I'll sand it down and then apply some teak oil, or maybe someone could suggest doing it a different way .
Just wish my grandma was here to watch it with me.
Thankfully, the damage doesn't look too serious on your cabinet, and I suspect it could be quite significantly minimised without resorting to a lot of hard work.
I did a little article on restoring, or moreover, recovering a badly mauled Bush TV24.. Granted, the Bush had a highly polished finish (originally at least) versus the "natural wood effect" of your HMV.. It could be worth a look at at least before deciding how drastic you need to get.
Don't forget to look at that black Callins capacitor in the audio amplifier section, if it's still there, change it!
Looks great with a good CRT, surprisingly so as these squared up types often gave some corner defocusing from new, think this model will date from 1969 with the squared up type of CRT.
Is that the tuner knob I found at Davids?
Can't wait to see it.
I would rub down those scratched cabinet surfaces with two grades of sandpaper.
A slightly coarse paper for the first rub down and and followed with a fine paper.
A clear French polish to finish the job.
I believe this cabinet style was introduced in 1970. A similar cabinet styling theme was continued in the HMV 3500 series CTV. Was it the model 2715?
Also the model 2725. 1975 to 1977.
The set must be at least 1970 as the mains lead has the blue & brown colours . I'm not sure but didn't the new colour code start from 1971.
Certainly leaflets promoting the new colours were published in 1969. The KB KV125 I recently took delivery of has red/black conductors and uses the VC51/2 chassis; whilst the one my parents owned used the VC51/4 chassis and that used blue/brown.
The VC52 (KV025/1) model I had used the new colour coding, I understand it was introduced on 1st July 1969.
