RE: HMV 2645 Thorn 1416 chassis

The junior school I attended between '72 and '76 had several of these sets. I had to move one of them once - it was heavier than I thought it would be. John

RE: Mystery American Philips Radio

Interesting that it uses the Dutch spellings for London (Londen), also Bandung (Bandoeng) and Surabaya (Soerabaia) in Indonesia. This wouldn't be so surprising if it was made in the Netherlands, but i...

RE: Ferguson 3847

I remember seeing many of these tellies in classrooms when I was at primary and secondary school in the '70s. Some of my friends with wealthier parents than mine had them as bedroom sets too. John

RE: Philips N4308 output stage fault

I've come across the odd AC128 with an internal short to the case before. As the AC187 has the same type of construction to the AC128, I would expect the same thing to be seen with the AC187. John

RE: Not A Ferranti 146

The trimmers are under the chassis in the 146, you can see the access holes in the top. They're still in roughly the same location in the mystery set. John

RE: Ofcom Small-Scale DAB

My 2012 Passat has DAB+ so I'd expect your Polo to have it too. I suspect that most receivers of current design would use a chipset that supports both DAB and DAB+. It is a shame though that the manuf...

RE: Hantek MSO5102D

I use logic analyzers from time to time in my professional life, but nowhere near as much as back in the '80s. These days, I'd typically use one to look at a SPI interface i.e. with clock, select and ...

RE: XHDATA D-808 Portable Radio

I received a XHDATA D-808 as a Christmas present and I'm quite pleased with it. I took it along on my recent holiday to the north of India just to see what I could pick up. As expected, not much on MW...

RE: 1977 Ferguson 3734 ColourStar: Thorn 9600 Chassis

Chris If W528 is really being killed, the most obvious cause would be excessive current flowing through it causing excessive dissipation. I suppose this would be possible if the W513/4 input to the tr...

RE: 1977 Ferguson 3734 ColourStar: Thorn 9600 Chassis
