Question Help! Questions re Linn LP12

Hi All! I recently acquired an older Linn LP12 and I can't figure out if the power source is original or a non-Linn replacement. I know the unit is older (i.e. probably pre-1985) but I do not know when exactly it was purchased.

Any advice on what you see in the pics attached would be most appreciated. I will gladly answer requests for further info.

Many thanks,
CC99

Go to the vinylengine library link which shows the history of how the LP12 evolved and the serial number sequence. This should give you a pretty good idea of when your table was produced.
Here is the Analogue Addicts LP12 FAQ page for more info.
I have an early wiring diagram in pdf format that I can email to you if need be. It looks like what you have in the pic.

Jeff, thanks for your helpful info. The SN indicates the unit is very early, around 1973 I suppose. SN=20555.

I cannot email right now (newbie status) but would greatly appreciate the PDF of the circuit you mention. Could you send it to me please?

My email is bubbachalubba@gmail.com.

Many thanks,
CC99

This mains noise filter is a horror! Was it made by a butcher's apprentice?

Once i had an even older Linn. There has to be a phase-splitting cap and a votage dropping resistor. The two extra cap are indeed to filter switching on/off noise.

Thanks for trying Jeff. The link works for me - no typos.

Couldn't post all pics earlier, so here are links for anyone interested.
