Well I find this discussion of cheap'n fun phono stages fascinating. I wasn't aware of the Rat Shack project, and now I am I think I'll have to give it a go! Thanks Joe and Eldartford! It seems to me that Gram Slee started by making a phono stage for 78s, you should look them up Albert, and see if it is still (or ever was) made. Unfortunately, my books are still all in boxes. I believe it was an early Hi Fi + that did the review of this 78 preamp (if it was a Gram Slee).
On the subject of the Mini Phono, however, I am certain of what's going on, as this is what I use when playing my Lencos. While my regular phono stage is quite good - which despite being a Pioneer Elite preamp from the '80s (avaunt Demon!) is of surprising quality (it surprised me), better than the NYAL I had used until I acquired it in fact (the surprise being I had bought the Pioneer as a stand-in until I could get the NYAL repaired) - it cannot handle the extreme dynamics of my Lencos (this is not hyperbole), so I use it strictly for my belt-drives (it has deeper bass than my Mini Phono): my Maplenoll, Ariston RD11S and Audiomeca, among others. The only cheap phono stage which will accomodate the Lenco's dynamics without distorting is the ASL Mini Phono, because it is tubed. This is a superb unit for the money, and has much fun tweak factor built in (as do all ASL units). It also has tube rolling potential for yet more future fun. I bought a pair of severely measured (specifically for the ASL's electrical characteristics) and matched Philips NOS tubes for mine and it is dead quiet. Not too much gain though, but not a problem, and I have the volume control on my preamp, which can go to 11! Given the Lenco's dynamics, the NAD and Musical Fidelity need not apply. The jump in price from the ASL to the other options is not subtle. And will they match the ASL's glorious tube midrange (truly, this is a giant-killer phono preamp, given matched tubes for quietness, which are absolutely necessary)?
If you decide to go for the Thorens, be aware that this is a "quasi-idler-wheel-drive", and so the dynamics will not match the Lenco's dynamics (the Thorens was found to be less dynamic than the true idler-wheel drive big Garrards in published comparisons), which means that the NAD and MF preamps can again apply, though I don't think they will match the ASL anyway. Being tubed, the ASL also has much more "educational" potential.
While it is true that many idler-wheel drives did have problems with flat spots and rumble, the Lenco is so designed so that flat spots do not develop. The sprung suspension of the motor also does much to eradicate rumble. This, among other things, makes the Lenco an excellent way to delve into the potential glories of idler-wheel drives. Bravo for your experimental and fun spirit Albert!
