Welcome to the Pete Riggle Engineering and Audio Forum:

Our products are: 1)the VTAF(tm), Patent Pending, VTA on the Fly for Rega arms and many other tone arms, 2)the VTAF Teflon Upgrade, and 3)the Counterweight for the Common Man.

Other products are in the pipeline, including a Large Bore VTAF which will handle those few tonearms with mounting post diameter greater than 23 mm, and hopefully a remote control for the VTAF that we are exploring.

The VTAF allows easy adustment of VTA with the record in play, so the user can hear the sonic changes as they occur. Isolation provided by the VTAF greatly improves sound stage, imaging, inner detail, nuance, air, bass clarity, and musicality.

The VTAF Teflon Upgrade adds to the isolation provided by the VTAF, thereby adding to the sonic benefits listed above.

The Counterweight for the Common Man is structural upgrade for Rega arms, which replaces the stock counterweight and stub, and greatly improves performance of the arm.

I have an abiding belief in the value of an enduring hobby. FDR was a stamp collector. There may be no better hobby in this world than Hi-Fi, especially DIY Hi-Fi. Hi-Fi brings music, lovely music, soothing, enjoyable, foot tapping, and inspiring, into our lives. One never runs out of ideas to ponder and try. You can enjoy this hobby any day of the year, morning, noon, evening, or in the middle of a sleepless night. And perhaps best of all, the Hi-Fi hobby appeals to some really wonderful people, from which one can gradually assemble a cadre of freinds and good aquaintances. Here in Southeastern Washington state, we have an informal collection of participants we call The Bad Boyz and Girlz Benevolent Association. We have great fellowship, a lot of fun with the hobby, and some shared projects.

Our goals for this forum are: 1) support for Audio Asylum (thanks to Rod Morris and his staff), 2) a place where users of Pete Riggle Engineering and Audio products, particularly our flagship product, the VTAF, can share their experiences with the products, ask questions, and get answers, and 3)a place for talk about things audio in general.

If you have an interest in any of our Bad Boyz and Girlz endeavors, please feel free to express that interest in this forum.

That is it for now folks. I'll be attentive to this forum, and do my best to answer questions as they arise. Have a great new year, and enjoy the forum.

Pete Riggle,

 Hi Pete,

First of all I have the VTAF installed on my Rega P25 and I love it. Being able to just dial in the sound of a record is just SO great.

My question though is that my RB600 wiggles around quite a bit in the bushing. The bushing is nice and tight in the arm hole but the whole arm moves about when I am raising and lowering the cue arm. Of course, when the needle is down and the record is in play the arm is at rest and doesn't move around. I'm assuming the tight tolerances between the adjuster and the bushing keep the arm in perfect position.

But is this normal to have so much movement of the arm? When I'm raising and lowering the tonearm with the cue?

Thanks!

Phil

 Phil:

With the VTAF I seem to have learned to operate the lift/lower mechanism of my Rega arm and my SME 3009 Series II unimproved arm without much movement of the arm during cueing. It will be interesting to see if other users will give us some input on this.

It does help to keep the guide assembly clearance fairly small to minimize wiggle allowed by the guide. On the other hand, the guide assembly should not be made tight, as getting it too tight can interfere with staying seated during VTA adjustment.

You are right that the small radial clearance between the VTAF Adjuster Screw and the VTAF Bronze Bushing does keep the arm mounting well centered. The .003 inch radial clearance between the adjuster screw and bronze bushing translates to a tracking error of .019 degrees, negligible when compared with the unavoidable tracking error of about 2.3 degrees characteristic of pivoted arms.

Can you comment on the sonic results you experienced when you incorprated the VTAF?

Yours, Pete, Pete Riggle Engineering and Audio
