BeBop Posted July 13, 2005 Report Share Posted July 13, 2005 (edited) http://www.rolls.com/new/vp129f.html I've been eyeing this item for about 18 months. I've heard that the gain is limited - my principal source of hesitation - but I suspect it'll be sufficient for my relatively high output MC cartridge. Much of the appeal for me is size. It does no more than a preamp with a MC/MM cartridge input and headphone output. No line inputs. The price is also right: $200 MSRP, with $150 prices widely available. And it looks cool. (FYI: Cool Counts) So I've taken the plunge. If anyone else has an interest, I'll post impressions when I've received and installed.

wolff Posted July 13, 2005 Report Share Posted July 13, 2005 It does look nice. What are you using now? What's the output of your MC cartidge? Around 2mV, I hope. It looks like the least expensive tube phono stage I've seen. It's missing a couple things(as far as I can see) I would want: 1) Variable impedance to match your cartidge. Looks like it's set for a MM(47-50k), and you say you have a HO MC. You may not get the best sound due to this. If you have a schematic or learn how to read resistor values, you could probably find the 47k resistor and swap in one that matches your cartidge(100k?). 2) Mono switch One nice feature is the variable output. You could try running it straight to your amp, thus avoiding pre-amp circuits. Quote Link to comment Share on other sites More sharing options...

It's a tough way to go, but ever since the dog knocked the horn off the Victrola. I'm planning to use this with my Sumiko Blue Point Special; 2.5mV, I believe. Agree. Variable impedance would be nice. Mono switch too. Probably both shortcomings could be addressed by a little at-home tweaking. And, on a $150 device, I'd be willing to take the risk. Amp? You mean, like, for speakers? Quote Link to comment Share on other sites More sharing options...
wolff Posted July 13, 2005 Report Share Posted July 13, 2005 Yes, for speakers, but it looks like you are using headphones only. Quote Link to comment Share on other sites More sharing options...
casanovas347 Posted July 18, 2005 Report Share Posted July 18, 2005 All-tube? They should explain how this work with a single Dual-Triode..... well, its still a cool item.....it looks great! Quote Link to comment Share on other sites More sharing options...
Eric Posted July 18, 2005 Report Share Posted July 18, 2005 http://www.rolls.com/new/vp129f.html I've heard that the gain is limited← Neophyte question - what does the term gain mean in this context? Thanks Quote Link to comment Share on other sites More sharing options...
wolff Posted July 19, 2005 Report Share Posted July 19, 2005 It's how much the signal from the cartridge is amplified. Quote Link to comment Share on other sites More sharing options...
