Default Pye Black Box

Does anyone have information on this.
Obviously I canít play vinyl on this as it could damage them?


Itíll be a easy job for me of course, the deck needs lubricating and some recapping is probable..

That seems to be an unusual cabinet, possibly made for the Irish market. It looks in very good condition!

Deck is a BSR UA6, so it's probably quite an early machine c. 1954, and is no doubt fitted with the E-series valve amplifier (Push-Pull or even ultra linear).

You must change all the little brown Hunts caps - a bit fiddly as the amp is very compact.

Beware the OP transformer might be open circuit on one side of the primary. Can be re-wound by an expert like Ed or Mike, at a cost of course.

It WILL play vinyl, it has 33 and 45 rpm speeds after all, but best stick to MONO records only. It may have had a stereo-compatible cartridge retrofitted though, in which case you can play stereo records too, but I would never play my "best" records on one of these (or any other 1950s autochanger for that matter).

Bargain for £20, grab it!!

Hi Nick,

Awesome, that photo was just the moment I bought it!
I will check the hunts and the transformer. Iíll probably put in a stereo cartridge. I doubt that another amp blackbox amp could be put in to make the machine stereo.. haha

Thanks Nick

Yes, that is the Irish version of the BB and made in 1955. You'll definately need a stereo-compatible or a full stereo cartridge. If you buy the latter, you will will need to bridge the LH and RH channels. You may jest about making it stereo, but the whole object of the design of these units with speakers sited at both sides, is that it will give a wide "stereo-like" sound stage when placed across the corner of a room. It looks as if the original Acos mono-only cartridge has been removed - if you post a close up of the cartridge (assuming there is one fitted) we can advise you of its suitability for stereo use.

Yes, that's the Pye 1004, their first transistorised BB from late 1963 with a hard-to-replace "All-Newmarket" germanium line up.

Age UK in Manchester £20..

The platter is stiff so reckon everything is seized. Do you have story on your £17.99 repair?

I think Iíll keep it mono but probably play 45s for parties.
I read somewhere that it is bassy? Is this true?

Does anyone know where I can get a exploded diagram of the UA6?

I wouldn't say they are particularly bassy, the tone control has a very subtle difference even when working correctly, however they do produce a lovely full sound especially when the lid is closed, I use a BSR X3M with mine and sounds great especially with mono records and very loud.
I've owned many vintage record players over the years and in my opinion these sound the best.

I'd guess turntable servicing information is available in the relevant section here? I think I have a Black Box somewhere from an elderly relative's house... I've heard they sound good, too!

So, made a start and this is where Im up to.
I dismantled and cleaned the turntable deck. This was the fun and easy part. All lubricated with grease and the speed selector as well. Both were really gummed up with grease and yukkily sticky. Nicotine?
When this was reassembled I took the amp out. I measured both electrolytic caps and both measured at 50uf. Measured the hunts half were way off and half were o/c. I replaced them all aside from one electrolytic which was meant to be 12ufÖ

I tried the amp and sure enough a buzz was coming from the pickup inputs.
I connected the cartridge, it was dead.. so I decided to open it up and my my was it filthy! It mustíve got wet at the time. I cleaned it up and re-straightened the foil. It worked but seemed quiet. A break in the pickup wiring was found and temporarily repaired.
The player plays well, aside from running a bit slow at 32.70rpm. (Is that any good??)
The pickup cartridge bracket is missing one screw.. does anyone have a spare??

For an elderly BSR UA6, that speed reading is very good! It would be well worth getting a new cartridge for this.
