Nothing to that: on the one had a collection of over 900 quotes and sayings accumulated over the years, and a prog I wrote that changes randomly the mail signature every half hour.

Thanks Chris, if anyone was going to know it was you! It's blindingly

but what on earth is the Carrier Fuse Cartridge No1? Note the number prefix
is given as 'Z' and not 'ZA'
The amplifier only has one fuse installed (500mA) so I can't see any reason
why an additional fuse - whatever it is - should be included.
Anyone know?
Yes. :-)

It's a spare of the fuseholder front that screws into the body, and is
present in case you break or lose the one from the amplifier (e.g. by
dropping it into the long grass/darkened recesses of your command tank,
etc.) while changing the fuse.

Same as the Case, Spare Parts, No.5C holding a couple of fuseholder caps,
connector clips and springs, dynamotor brushes and flick locking screws,
etc.

Re: Amplifier spare valve box contents

I read that the RCA VT60 and the Cossor-ish VT60A, with ceramic base and ribbed anode were 807s selected to be able to work at higher frequency than the bog-standard 807 [120MHz versus 60MHz]. This may have been formalised in the 8018 version, on which data is scarce.

Personally, I have never been able to find any evidence that ceramic based 807s had a different electrical spec. to the brown plastic based variety, except for a distant memory that the ceramic bases “resisted flashover at high altitudes”.

 

807s used to be popular with the Audio brigade, until dethroned by the [related] KT66 – perhaps due to too many close encounters with 807 anode caps? ;0)

Thanks for that. 

 

I knew the 807 was a major workhorse of transmitters but wow, so many different designations. 

 

Is there any discernible practical difference between ceramic and other bases.

 

BTW do you recall the designation of the Plessey aerial multicoupler consisting of about 6 cathode followers using 807s?

Thanks for that.

I knew the 807 was a major workhorse of transmitters but wow, so many different designations.
Worse than that, there are three different uses of "VT": Air Ministry (Valve, Transmitting), U.S. Military (Vacuum Tube), and (British) Post Office (BPO/GPO) also used (Vacuum Tube) - and _none_ of the numbers match.

Is there any discernible practical difference between ceramic and other bases.
Better insulation, so recommended for high altitude and (I think) humid environments - hence the Air Ministry using the ceramic based version. (I think the RN also used them.)

BTW do you recall the designation of the Plessey aerial multicoupler consisting of about 6 cathode followers using 807s?
No, but it sounds distinctly Naval in application. (Though apparently Bletchley Park designed/built something similar using 807s for running multiple intercept receivers during WW2.)

Best regards,
Chris.
