- Despite what the idiot says, this is a Hacker Gp42 not 32. In this part of the series I have a look at the overall condition of the machine, and check over the electrics. Initially the plan was to do a full recap, but after testing the caps for leakage and capacitance/ ESR I deemed this not necessary for now.

Great video Simon with a detailed explanation of the circuit operation that was very educational and I enjoyed. C clips are the work of the Devil
Hello Simon. Boy, that tube tester brings back memories. It was my first tester as a teenager. I sold it years ago, & now wish I still had it.
Nice to see you here! Yes nice little tester.
Great video Simon. Good explanation of how it all works and nice to see the valve tester in action. They are great sounding record players and it looks like a keeper for sure. Cheers Graham
Cheers Graham.
That's a nice player you found, Simon. Always thought Garrard was better than BSR. I liked the way the 78 section of shaft came of easy to allow bearing removal. Thanks for uploading, Daz..
Glad you didn't need to replace the ECL86 Simon (we know them as 6GW8's on this side of the pond). They are a bit pricey these days. A NOS tube is $60 or 43 pounds in the US. I'm not sure if the currency exchange rate applies directly because of availability in the UK. It may be more or less. Thanks for the look see. Stay well. ATB Doug.
Luckily they seem to test OK. One valve/tube costs the same price as this record player!
That's a real nice find Simon. Thank you for sharing the video. Good luck with the next installment.
Thanks Tony.
Superb , really enjoyed the Valves being tested
Looking forward to the next one
Best regards Shaun
Cheers mate.
That's in great condition, very nice find. Lovely engineering and assembly on the amplifier section as you'd expect from the UK's foremost radio manufacturer. One question, that large clip on the cover, is that for a complimentary Thermos or maybe a bottle jack?
Lol. That's to hold the adapter for the thiny that holds the 45's when the middle has been punched out for a juke box.
Boots did sell records and Electricals back in the 60s&70s
I wonder?. It would make sense as the date is about right. Thanks William.
Lovely Video Simon And a Superb Example Of a Classic Record Player Well Laid Out And Nicely Made... Hacker At Its Best Thanks For Uploading Looking Forward To Part 2 Stay Safe Regards mike.
Cheers Mike.
Enjoyed this. Thanks for sharing.
The SP25 was a single play deck, which featured in some Gondoliers, rather than the autochanger in this one.
Superb Mr Spiers. Is Hypoid 90 ok for lubricating turntables or should I go with standard treacle?
Yes a bit thick really. Me and the oil!
Not that is mattered in the end but as the ECL86 is a 2 section valve you only tested one part of it, could have been either the triode or the pentode. The Garrard 3000 is a lower spec SP25 fully automatic. 2 pole motor, the later SP25s had a 4 pole motor. Slower speed, less vibration. I think from memory (not what it was) the platter was just a metal pressing. The later SP25s was a part metal, part casting, not bad for a low cost TT.
The cartridge was the main let down on that record player, cannot remember what it was, BSR, something horrible anyway. The 3000 was often fitted with a Sonotone 9TA/HC cartridge. By ceramic cartridge standard quite a low output but really low compliance. Probably one of the best available, sounded as good as cheap mag cartridge, G850 etc. Such an amplifier, as used in this player had enough gain. That simple mod turned it into a really quite nice record player.
Thanks Michael, realised that the TC109 Sencore would not properly test pentodes after I did this. I have another tester I will try them on. The cartridge is a Acos gp96-1. Been looking at the BSR's as I would like some high frequency boost. Any suggestions for this? Tempted to fit an RIAA amp and magnetic cartridge. Do you think a SP25 would be a better deck?
Don't like this 3000 much.
@@SoddingaboutSi The Sontone 9TA cartridge I was talking about now goes on EBay for a jaw dropping 90 pounds. New price in the 70s about 5 pounds. Stylus are available as new stock. So if you find such a cartridge jump for it. A better bet might be a low cost mag cartridge, with, as you suggested an RIAA preamp. Something along the lines of a Goldring G850 or Shure M75/6 or similar. I would not really bother for use with the 3000. The arm not really made for any kind of mag. Or autochanger. If you have access to a later version of the SP25 MK 2, check it has the same cut out mounting board first, cannot remember. The SP25 came in lots of different versions, some quite crappy, some not a bad low cost table. Look for the cast turn table, not the pressed one. Find a cartridge that will track at 2.5 grams and a conical stylus. Don't use an elliptical stylus, or one made to track at below 2 grams, the arm has far to much mass and way to stiff, poor bearings. Also look for a version with the 4 pole, so called LAB Motor. Runs slower than the 2 pole (obviously!) Better speed stability and less vibration. The 2 pole version always runs fast at 240 volts. That combo should make a really nice, not HiFi, domestic record player. I'm sure you can find a low cost, kit probably, on Ebay for a few pound as a preamp/RIAA board.. You MUST of course video the job.
BSR did make one reasonable turntable, the MP60, only issue the motor board cut out is completely different.
If you do simply keep the ACOS cartridge, that's probably better than ANY BSR made. BRS are mostly high output, no compliance and nothing but midrange, as far from HiFi you can go, usually tracking at 5/10 grams. Great for destroying records.
PS Lots of RIAA boards on EBay 10/15 pounds, some with power supply and everything.
@@MichaelBeeny Thank you Michael. So here is one more question. Does BSR stand for
1 Birmingham Sound Reproducer?
Or
2 Better Sound Reproduction?
@@SoddingaboutSi Hi Simon, to be honest I'm not sure. I think probably the Birmingham version. I think the later is possibly optimism!
@@MichaelBeeny Totally agree with that!
Much enjoyed, Simon, a nice neat record player.
Cheers Theo
Assuming the rectifier valve had been faulty, would you have gotten a new one or put a solid state bridge in there?
Well that's in a very nice condition and the amp looks very nicely made :-D
Did you find the volume control fault? or has it vanished to pop up and annoy you another day lol.
As faults tend to.
Just a few components to check and a couple of minor repairs and it's basically done :-D
In the lid there is a clip for a container maybe, spare needles perhaps?
I think it was tarnished connections. As soon as I removed the amplifier to volume control lead it started working.
That's to take the adapter for the 45's when the centre had been removed for using in duke boxes. Think the loss of volume may well be back.
@@SoddingaboutSi I wonder if they ever made one with a tuner as well as the record player.
I bet they thought about it, ' The Gondolier Supreme.' lol.
1 MEG volume and treble controls ? Sounds noisy... did they know about Johnson noise then?
Had to look that up! They may have but I doubt it was a problem in gear like this?
No points for getting oil on the idler. Old araldite syringe, clean with hot water, tube from shave foam, stuck on end makes for a reasonable precision oiler
I had to laugh when I said a drop of oil is all that's needed, then flood the bloody thing!
@@SoddingaboutSi these things happen, I still enjoyed the vid especially the detailed explanation of how the dim bulb is actually used on the job, ty
How do I engage you fix fix my Hacker which sounds horrible for some reason?
Might just need a new stylus?
@@SoddingaboutSi Well, it's looks alright but I'm not sure where to get a quality replacement. It's in fabulous condition so I want it to live on!
