Virtual espresso for you

Thanks. Tastes very good. now on the hunt for a 1000uf cap. in the parts box. I have a 35v specimen but I don't think that's sufficient.

 

[mkane77g]

I used a 680uf/450v cap. Next best thing is 1000uf/32v

32v is not enough, so good choice with the higher voltage!

680uF will be fine.

Thanks. Something sunk in doing DIY stuff. When in doubt go big.

Biiiiig cap!
Let's spin!

Nestled right in where the PS used to be with a bit of blue-tac for support.

 

[mkane77g]

Here again. This is a worthwhile upgrade. The biggest impact is in between notes and quiet passages. A cleaner sound if you will.

Strobo wires are brown and red.

Cut the brown one, not the red one. Not the red one !! ...

 

[mkane77g]

We made too many cuts. Good thing for heat-shrink. I'm wondering when I attempt to do the ps mod will I be able to desolder the correct pieces without removing the pcb.

Nothing esploded

 

[mkane77g]

Nope, all is well.

A pleasant surprise in the mail.

Somethings haywire. 42dcv @ PS. Deck doesn't spin. 33 1/3 light is on. It won't switch to 45. Any thoughts?

I presume this is voltage directly from your power supply. What kind of voltage are you getting at the on-deck regulator? Since you have moved the PSU outboard, I presume you've removed the bridge rectifier from the PCB. Where have you attached your new PSU to the deck?

Also, DO NOT hit the start/stop button without the platter installed - this will cause damage to the circuitry.

Thanks Eric. It all went to hell yesterday. Messed up PS for sl1200, tipped over motorcycle which caved in the door on the car, busted fairing. Fed up, pushed the deck under the bed.
