Presto 6N guidance suggestions? (piecing together)

[tragwag]

awesome!
I've got the presto R-27 tape machine with A920 amp.
Can't wait to get it up and running.

[MBL]

The A920, is that the single channel mixer/preamp? Does it have a balanced or unbalanced output?

Would one of you trolls out there with a 6N mind lifting your platter and taking detailed pictures of the motor mounting? I am missing the motor mount bracket and will need to fashion one. Measurements would also be very helpful!
Thanks for your continued help!

Ok so the more I look, I think this the right motor, but I don't have the mounting bracketry.





Anybody got some good pics of theirs? I think it says 1/25 hp and 1500/1800 rpm.

[MBL]

I mostly assembled an overhead here. I think I have it correct.

I'll try to take some pictures of the motor in place, I'm doing some tuning on it anyway

[MBL]

Hello i have pictures of the motor mount in this topic about the speed problem i had awhile back.

Thanks for the pic! It'd be great if I could bave something like that CNC'd.
Hmm?

Any chance you could take some pics with a ruler against the bracket parts from various angles? I would like to find out the height of the risers the are on the motor bracket itself...and perhaps the table bracket as well. And I guess how far the curve extends from the flat parts on the ends. I actually have access to a tracing of the motor bracket but not the one that is fastened to the table.
Thanks again!

So I keep on tinkering and tinkering. I want to get a proper switch for this table. I have a On-Off-On switch I bought, but not only is it not able to be adjusted to allow the proper amount of travel, it occured to me that it should be a momentary switch...otherwise it wouldn't automatically snap back when you moved to the middle selection unlest you did it manually.

I realize a push button switch was used as well as a toggle. Has anyone found a decent replacement switch that works as originally intended?
Thanks

What are all of you using for monitors? How about monitor headphones? I pulled these old tweed monitors out of the attic, but have not yet decided how to best use them.



How does everyone here drive their monitor system? Do you use a separate PA amp?

Still working and collecting. I managed to get this Collins 212A-1 Broadcast console. Gonna need some work. Missing one big knob and some buttons. Anybody out there have parts for these?

Once again, it seems I am in the presence of equipment porn.

That console is a beaut. It's a dream of mine to piece together an analogue studio from roughly that era. Nice find.

[MBL]

I managed to find the correct meters as a pair...and the missing knob was actually stuffed inside the console. I still need a handle and some of those little buttons.

Ok, so a little developement. I managed to get another Presto 6N table and lathe together. This one has the 190-A equalizer and rack mounted companion switch.





And I'm gonna permanently mount a 6N overhead to the Micro Engineering transcription table.



Got my work cut out for me.

Doing more cleaning. I saw that newer turntable does not have the large ball bearing thing like the first. This one seems to have a small ball bearing stuffed into the shaft of the turntable itself. Is this normal:



It seems to spin fine, but I wanted to make sure I am not missing a bearing.

Also, it seems there is some sort of transformer involved with the motor circuitry. Does anyone else have this?
