Techo Baz, hi, Those 'portable' record players certainly bring back memories of my early years as an apprentice audio and television service tech. Starting as a sixteen year-old (1971), virtually all those type of record players, along with older radio, and television service jobs were passed over to myself and an older fellow apprentice (apprenticeships those day were a duration of five years). I lost count many years ago how many of those record decks I have serviced. One thing for sure, we didn't service them to the depth you serviced that deck. There wasn't sufficient time allocated as "money was time, and time was money" - as workshop managers constantly drilled into us apprentices - we were a source of cheap labor. Certainly enjoyed viewing this entire service video series in one sitting. Regards, Phil.
Good to see this little portable going again. I'm sure its owner will enjoy it. It reminds me of a portable HMV I fixed up a while ago. Same sort of amp and the performance is a bit underwhelming but that was acceptable for a cheap record player in those days. Cheers
Always a little bit more to troubleshoot when completing a project. My first thought was the actual shielded cable was bad, but the grounded speaker causing the problem would throw any technician for a loop. I think the slightly fast speed to be well within spec unless it was a high end Garrard or other component turntable. Good job!!!
Yes Doug, that speaker threw my indeed. Strangely both terminals are insulated. I checked them later continuity to the speaker frame, guess what . . Open circuit ! Yet touching the shielded cable to the frame shorted the audio. I'm rattled with this one !😵💫
@@techobaz55 Another baffling electrical problem was with my kitchen lights. I had a paper shredder develop an internal arc in the motor and it caused the kitchen lights to turn on with the switch in the off position (mercury switch). Kitchen lights and shredder were on the same circuit breaker. Then when the switch was turned to the on position one of the two fixtures turned on and the other off. Finally it straightened out. My theory is that the arcing in the paper shredder motor temporarily vaporized the mercury in the switch completing the circuit in the off position but the odd way the fixtures alternately turned on and off still remains a mystery. They are LED lamps.
Yep, you have it in pieces, it's all working and once you put it all together..........nothing lol. The bane of all Techs Baz. I hate it. A very thorough job and great that you saved a dinky little record player from being binned
LOL, yes Frank, it's not the best feeling, especially on something really simple. Thought I would leave it in the Vid, someone else might get caught with similar stupid error ! Cheers

Thank you for watching Phil.
So many memories indeed, this one was just good fun.
I better get onto something more serious !
Nice little project Baz. Enjoyed watching the progress.
Glad you enjoyed it

It belongs to a tv station, used as prop but probably will never be played !
Baz that is exactly what I thought it was doing! Grounding out!
The thing is, why is both speaker terminals insulated & neither show any continuity to the speaker basket ? It's got me this one !

@douglashoff95 very interesting 🤔
Good one, Baz.
Thanks for watching Bill !
Baz Another gutless wonder live again my Congratulations in getting it going again ,Ian,
Thanks again! 😅

@@techobaz55 I think small but irritating glitches are the best thing to show as they happen to everybody :)
Just thinking if you had reversed the speaker wires it would (should) have solved the earthing problem? Not worth taking it apart again now, though.
No, left it Don. No continuity between either terminal & the basket, yet it mutes it. Got me !
@@techobaz55 That’s just weird. Bets me too.
What was causing the speed to be off? Idle tire wasn't right size or motor needed a resister!
I didn't worry about the 1rpm, owner wasn't worried so no more money spent. A resistor wouldn't be good with a varing load.
