Sorry Dave. I'll send you a box of tissues to mop up your tears.

Keep a look out for a Mazda CRM172. They are usually good. I think that regun you have has become a bit off spec. You can use the Mullard MW43-64/69. The neck is a tiny bit fatter but if my memory serves me correctly, it will fit.

I have a 21" V320 that I fitted a Mullard MW53-80 in place of the original CRM212. It works 100%. John.

That surely is an excellent picture there John. I noticed in post 19 you said there was tuner coils fitted for channels 1,4 and 8. Was there any evidence of any channel 9 coils ever being fitted? How many positions are there on the tuner knob?

Alan.

Just four positions on the Murphy tuner. It does not have a fine tuner, only provision to reset the oscillator core in the unique 'biscuits'. This is a long plastic tube from a tiny hole adjacent to the channel selector that allowed adjustment via a special Murphy tool supplied to dealers. The coil biscuits are of a blade pattern rather than the familiar studs. I don't think I have ever had to clean this style of coil assembly. Murphy engineering at it's best.

The pictures show more clearly the internals of the tuner. Indeed, when viewed under a strong light the coils are coded for channels 1-9 and 4. I suspect it may have had a set of channel 8 coils fitted originally as this would make sense, London and Birmingham.

The wafer switch fitted on an extension to the tuner spindle selects the separate preset gain controls for Band 1/3. There is zero frequency drift, quite amazing.

[Another Forum member who shall remain nameless insisted on foisting this china pussy cat into my clutches. I think he paid 5p for it at a church jumble sale. Just to prove I didn't drive a Blaw Knox over it I have included it in the picture..So there!] John.

Thanks for that John. I have never seen one of these sets in the flesh so was curious as to the number of positions on the tuner knob. Amazing how they made it so stable for the technology of the day. Most of the sets of that vintage sold in the Midlands at that time with turret tuners with individual 'biscuits', almost always had coils fitted for London-1&9 as well as 4&8. If the set was to be moved to any other part of the country the appropriate coils would have to be fitted at the new location.

Successor of the Murphy V310 was the model V410. The new set was introduced in late 1958 and was the similar in appearance. The installation of a 90degree Mazda CRT allowed for a slightly slimmer cabinet. The full spec chassis was similar in many respects to the model V310A in having sync cancelled AGC and flywheel line synchronisation. And like the V310 the V410 had the famous "sound mirror" flip-up control lid.

Before finally boxing up this evening I finished giving the chassis a light clean. Just a paint brush and Mr Henry. The Bakelite tube surround was brought to a nice shine with a little effort and a dab of Brasso.

It really is a grand receiver. My phone camera tends to flatten out the peak white content of the picture but it does give an idea of what it is capable of.

Both timebases have a solid lock with all the original presets working as they did back in 1957. interlace is 100% something I have noticed Murphy were very fussy about.

It is about as good as it gets. 405 lines in all it's glory! Full entertainment value with a brilliant 17" Mazda CRM172 CRT. [Mazda certainly knew a lot about phosphors and aluminising.] It is very watchable with moody scenes appearing as intended with excellent black level.

A very easy repair needing only replacement of the wax capacitors, cleaning and adjustment. Regards, John.

PS. Peter, I thought that was the name of a KB television receiver..

Can you imagine the reaction from buying public when the Murphy V310 appeared in the shops in the early summer of 1957? In fact the owners of these sets had little compulsion to replace any of the V310 series models when the latest "slimeline" TVs appeared in 1959. The depth of the cabinet didn't matter because of the unique styling.

Lots of V310 sets were still use into the early seventies.

The V310 must have sold in very large numbers. It must be one of the very last over engineered chassis and been costly to produce.

How Murphy did this even back in 1957 is a credit to them.

The scan shows the complete service area models in the V310 range. I have never seen a V310C with the 'swing screen'. Note the prices at the bottom of the page.

Purchase tax varied but was around 33% being replaced by VAT in 1973. Note these are retail prices. J.

A cool looking set with a lovely picture John. Looking at your attachment, that V310C on the pivoting U - shaped stand is something else! A lot of the Murphy products almost look as good on the inside as on the outside with the chassis construction looking like parts from an aircraft or spacecraft.

Yes, the V310C is a very unusual set and I did acquire one in the 1980s from a retiring radio and TV dealer who's business had been selling Murphy products since the 1930s.

Unfortunately, one of the two moulded parts that fitted onto each side of the cabinet and then sat in two supporting metal brackets fixed on either side viewing of the U shaped wooded stand (and thereby allowed the TV screen to be adjusted to various viewing angles), disintegrated. This, coupled with a need to slim down my collection of TVs, due to a reduction in storage space, caused me to move it on. However, it is in the very safe hands of a Murphy collector.

Styling of the V310 was something else and was a thing of beauty.
