Default Another oddity found in the workshop.

Hello,

Another of my random musings, nowt more than that…

I picked the FM tuner module in the pictures at a RWB a couple of years ago and I know absolutely nowt about it.

The only identifying marking is ST-300 and some numbers on the track side of the PCB.

Anyone identify the tuner in the pictures?

Terry

It looks like the sort of thing that Henry's and the like might sell.

Yes, I'd place it as being from the mid/late 60s, only going up to 100MHz means it's unlikely to be a later design.

Henry's, Lasky's, Stern-Clyne, RSC, all sold similar things.

It actually appears to go to 108, but I agree the construction looks late 60s. The transistors appear to be silicon.

Ah, I was looking at the logging scale along the bottom !!

Looks to be similar to this Japanese tuner that seemed to be available from every electronics shop in the 60s. Would have loved one of these back then to save asking dad every Sunday if I could borrow his FM radio so that I could record the chart.

Yes, I think you've found it.

Well found Peter. I'd have put it later in the early to mid 70's what with the blue Philips axial cap and tinned PCB traces, very similar to early Akai R2R' PCB's.

Hello,

Thanks for all the replies, it’s really appreciated.

Ah, it’s been found, anyway looking at the advert let’s hope the buyer wasn’t disappointed

I feel the blue Philips electrolytic capacitor was a retro fit to add some extra decoupling.

This came along with a home/workshop brew amplifier comprising of a Bailey-Burrows Preamplifier feeding the original Linsley Hood Class A amplifier. These both date back to the latter part of the 1960s, so it fits with the date of the PW.

The preamplifier and power amplifier is a cracking build, typical of a really nice home/workshop construction even using a homemade PCB in the preamplifier!

Finally, I vaguely remember a construction article in Radio Constructor in the latter part of the 1960s using this tuner feeding a power amplifier using OC35s or suchlike.

Terry.

I was amazed that "Sing Something Simple" kept going until relatively recently! Maybe 6-8 years ago IIRC.

Unfortunately BBC cuts mean that many of the best shows (IMHO anyway!) are ending on many of the BBC local stations. In just the past month 3 shows I've just discovered on BBC sounds, all folk or jazz, have broadcast their last episode. No doubt stuff I'd consider execrable like rap and rave etc are not about to suffer the same fate!

My 1972 Henrys catalogue lists it as the A1005 priced at £6.75 and they also list a version in a wood case (the A1008) priced at £9.75 and a matching stereo decoder for £4.99.

I built my mother a radiogram using the A1005 tuner, together with a home-built transistor amplifier, & a Garrard Autoslim autochanger. I bought a cabinet from Dukes in Romford road London to complete the job! I have a colour slide picture of it somewhere...
That must have been around 1971/2.

The tuner was a little fiddly to fine-tune as the simple drive cord/pully wasn't that precise, but it worked tolerably well. I don't think my mother ever moved the tuning control from the Third programme.

Hello,

I kept thinking about that project in Radio Constructor using Henry’s Radio transistor tuner type A.1005. I kind of knew the years to look at and I found it relatively quickly in the February 1972 Radio Constructor magazine.

It’s on the PDF pages 34-39 in the PDF in the link below:
https://www.worldradiohistory.com/UK...RC-1972-02.pdf

A few of these homemade radiograms get righty or wrongly stripped down mainly because of their size etc., and the amplifier and tuner parts find themselves being sold at jumbles and meets etc. This was the case with this tuner. As I said the amplifier is nicely made and because of that I now look out for these units.

Agree, the drive cord/pully on this example leaves something to be desired, but it works.

Regards
Terry
