Who needs a MM cartridge type when we have MC?
Dear Raul, that is a wonderful litany of options from Axel. I'll wait for his response to my email. Running in this old M320 on my linear tonearm has been an amusing exercise. By tilting the air manifold of the linear tonearm down toward the recor... 
Who needs a MM cartridge type when we have MC?
Lew, FWIW the Silonex variable LDR and the 200K fixed resistor are attached together on the phono PCB. There is no additional wiring in the signal path. 
Who needs a MM cartridge type when we have MC?
Dear Raul, For resistive loading I use a Silonex light-dependent variable resistor in parallel with a fixed 200K TX2575 resistor. At least one or two MM cartridges preferred loading above 100K, but the experiment was done a few years ago shortly b... 
Who needs a MM cartridge type when we have MC?
Thanks, Harold. I just grabbed that 320 III STR for a try on my Terminator. 
Your First Concert was.....
Arlo Guthrie doing Alice's Restaurant circa 1968. Thereafter and more memorably, Steppenwolf-- John Kay in leather pants and dark glasses, Goldy McJohn's giant red afro bobbing over a vintage Leslie, and Nick St. Nicholas with a bass guitar hangin... 
Lightspeed Attenuator - Best Preamp Ever?
Augwest, IIRC the BBAM is a capacitive load with 40K input impedance. This could present a difficult load to an LSA passive. In my instance the challenge is compounded: I split the preamp's output between the downstream BBAM and a sub with 47K inp... 
Beware MSS Hifi, avoid Fraud

Practicality of footers to isolate turntables.
For an unsuspended table with an outboard motor, put the entire assembly on top of a single thick maple butcher block and elevate the butcher block from the rack with 5-6 soft industrial springs. Clamp your stock footers tightly up against the TT ... 
Best inwall speaker 4000$ pair
Miracle Audio speakers are the only reasonably-priced flat wall speakers I've heard that have audiophile sound quality. The Wisdoms are great but expensive. 
Lightspeed Attenuator - Best Preamp Ever?
Augwest, are you placing the Merlin BBAM upstream or downstream of LSA? 
Best Rock Album in 2012
Pete Townshend Quadrophenia Demos 1 & 2 (released on vinyl EPs in 2011 & 2012) argue that at his peak Pete was the Beethoven of R&R. 60% of The Who release is on these demos. What was saved or cut makes for a fascinating schematic of p... 
Soundsmith Straingauge SG-200 cartridge system
Spirit, converting any phono stage to 100K loading for vintage MM/MI cartridges is as simple as replacing the two or four 47K or 23.5K resistors located closest to input. Switching any remaining small-value load resistors in parallel with 100K wil... 
Soundsmith Straingauge SG-200 cartridge system
Spirit,Here are alternatives that will work well on the Trans-Fi and set a high bar for comparison to some of the top new-production cartridges. It is catch-as-catch-can with vintage.http://www.ebay.com/itm/VERY-NICE-CLASSIC-PICKERING-XSV3000-CART... 
Soundsmith Straingauge SG-200 cartridge system
Spiritofmusic, I have not heard a Zu 103, but have passed through Denon's top DL-S1 on my Terminator as a side-bar to a fairly wide range of NOS MM/MIs. FWIW the vintage MM/MIs will flip your wig. I've heard the Strain Gauge at several trade shows... 
Active FETs vs. Step-up phono stage designs
Lew, another hobbiest has used MAT12 interchangeably with MAT02 in this application, so I don't think there is any issue.
