I'm pleased to report that Pete Riggle has already replied to me, and is making up a smaller adjuster wheel. That's good, reassuring service. Having replaced the other armboard with the Jelco mounting collar onto the Technics, I sense that the deck is sounding less 'free' than with the VTAF; indeed it sounds relatively 'matter-of-fact'. Far too little time to make conclusive comments, of course, but encouraging for the VTAF nevertheless.

So, for those interested in following this little experiment, please be patient for another week or so.
