That worked Marc. It's dialed in now.

Massive huh, that can only mean one thing...you added the T-50 to the package! You're a great guy Marc! Most people wouldn't give up such a nice headphone so generously.

Inverting the switch settings for 45 RPM is way too slow. The motor barely starts spinning the platter at first, and it's closer to 33 RPM than 45.

OK, 45 RPM is at 5.70V and 33 RPM is at 5.02V.

I'm on my way to dinner, but will try inverting them when I get back.

With one lead removed from X3 I'm now measuring 5.21 V for 45 RPM and 4.55 V for 33 RPM. I'm sure that removing one side at a time for the Pearl will be easier to deal with anyway.

The knob detent for 33 RPM is right smack in the center at correct speed. :dance:

OK I got the VR1 dialed in at the 5.75 V I had measured for V1. The speeds changed for sure. I'm still able to dial in 33 RPM with some adjustment left at the knob. 45 RPM won't quite get dialed in at this setting though. However knowing that I can revert back to moving the jumper if needed, I'm going to leave it as is. I'll be playing 33 RPM records 99.99 percent of the time. That was fun BTW! Am I an official begginer DIYer now?

With the meter in the Ohms position at the 200 mark I got a reading of 65.6 Ohms. I guess I'm not understanding you correctly here, because if I remove one of the motor leads at terminal X3 I don't have any power to run the platter at 45 RPM. What am I missing here? Oh and BTW My jumper at JP2 was already connected to pins 1-2 (in the right hand position). Not sure if this significant.

OK, These switch settings work beautifully. I can dial the 33 & 45 RPMs in perfectly, and still have plenty of adjustment room at the knobs.

OK, 33 rpm measures 4.96 and 45 rpm measures 6.49. I hope that tells you something meaningful, because it sure doesn't mean much to me.

But you pay what you'd expect for the Koss. IMHO the Koss is a big bargain, and a very under rated stat, especially when coupled w/a great amp and running at the Gilmore recommended voltage. I also find the Koss quite comfy, and build quality is not bad.

^ Grawk that may be worthwhile for you, if your interested.

My guess is about 70-75 Lbs.

Just ordered a custom clear acrylic one piece dust cover for "Colossus". It should be here within 3 weeks.

I really like that it has a tilting table, and it looks like a very well made unit.

OK Marc I got the CEN-TECH multimeter tonight. Can we do this tomorrow maybe?

OK, I have to go into Corpus and pick one up first.

That sounds great. I'll need better instructions on tweaking the speed controller with the piece you gave me as well. My strobe and strobe disc came in yesterday, and both 33 & 45 RPM are a little past the the settings we have now. They're not far off though. I've inquired about a custom dust cover too. We'll see what they have to say. I actually missed the fidgetyness (is that a word?) of a vinyl rig. It suits my personality.

Cool, 100 Ohms loading will be great. This is something I can most likely do, once you map out the right location for me?

Me too, Happy belated Birthday!

Well with a big thanks to luvdunhill (again), we got her up and running at Saturdays Houston meet. Marc brought about 10-15 Lbs. of lead shot which I used every ounce of. He got the new cartridge mounted, and schooled me on some of the finer points of tweakage. We got her sounding pretty darn good. Considering the limited time factor, wobbly table and such, I was very impressed. Beginners luck for sure, because I've never built a plinth before, but good advice goes a long way. We didn't have a lot of gain for sure, but I bought a step up transformer last night, and it should be here in a few days. We did get a very quiet background even with the β22 cranked to max volume. Marc the table does have noticeably better low end set up here in my system. I'm guessing it's the solid 3" Maple slab under it. It's dead level now too, which wasn't easy to get on that folding table. I'll report back after the Consonance PM-3 step up arrives. I'm quite pleased with the Zu DL 103 though. Here's Marc getting ready to settle in for first listen.

Just listened to mine Saturday at the Houston meet. Dead quiet, no issues w/the toroids whatsoever. Beautiful build Marc!

Interesting. Can't wait to hear them tomorrow. The Blue Hawaii too. I think the Buffalo will leave you with a positive impression though.
