Rega P10 v Complete rebuild Garrard 401!
Seems quite costly over there in the US for anything Garrard. Check out eBay UK here for a decent 401.

The kids will put in the cupboard and use their phones instead. 
Moving tube equipment
Travel with them in the amp. My experience is they should be re-biased when you get to the new location. Over time tubes settle in an expansion-contraction pattern when you switch them on and off and rattling them during the move disturbs that sli... 
Rega P10 v Complete rebuild Garrard 401!
@bukanona, my 301 idler is a bit shiny and has small cracks developing so really needs renewing. Also the motor pulley is shiny polished and won’t grip the idler very well. So need to renew both. While I’ve got the RPM app out I should swap the go... 
Rega P10 v Complete rebuild Garrard 401!
@noromance, My 401 measures 0.11% wow and flutter on the RPM iOS app. I have the Kokomo bearing upgrade on mine. Can’t find anything about the SPH bearing on the net? Sounds like a worthwhile improvement though. My worn 301 manages 0.16%. The tone... 
Rega P10 v Complete rebuild Garrard 401!
All I can say is that I like my 401, flaws and all. I love the dynamic and musical sound, as well as the way it looks.Sure, other turntables are technically far better and you can go down that road if you like. I’ve owned some of them. But I am ha...

Ha! audiokinesis, diy could be a gateway drug, that’s so true!I started with speakers as a teen and now design and build amplifiers....

Regarding rumble on a 301 and 401, they don’t put out any subsonic rumble so will work fine with a subwoofer. It’s just a slight background noise like the idler wheel spinning, which it is. It’s very low in level, quieter than the record surface n... 
Rega P10 v Complete rebuild Garrard 401!
Can’t really speak for Rega’s new P10, I’ve only seen it at a hifi show and the look isn’t quite to my taste tbh. I’m sure it’s a great TT though, they have spent a lot of time refining the lighter and stronger design concept and I’d love to hear ... 
Power Amplifiers
Sansui CA-F1 and BA-F1 pre-power combo, partly restored, still get switched on every now and then. Still a transparent sounding combo after they warm up over an hour. 
Futterman. Jump in? Or, not so fast...
Roger and I had some great discussions way back when about Futterman circuits. The genius was getting a pentode to operate at low plate voltage with high screen voltage, operated by a bootstrapped driver pentode. The oscillations partly came from ... 
Sansui CA 2000 preamp
Glad it fits into your system well! Especially regarding the low noise with sensitive speakers. A low powered amp would work well with them and a single ended tube amp might work well. At 100dB efficiency all you might need would be a 300B amp wit... 
Through unfortunate circumstances........
To use your Yamaha HTR-5660 with your Pioneer Spec 1 preamp, you’d run an interconnect from the main RCA output of your receiver (the main output rca sockets are just above the left hand side of the speaker outputs), to an aux input or tape input ... 
Balance knob ..
Is it a speaker positioning problem, or an amplifier etc. problem? I’d try to work out where the problem lies before resorting to use of a balance control.Try swapping the channels at the speaker leads to see if the balance issue swaps channels. I... 
EAR founder has cancer
Oh. Poor Tim!Better go and see him properly soon, he’s here in the UK. But chatting to him isn’t straight forward, I’ve learned. We’ve had some great chats over the decades. I was only wondering the other day after seeing him at Munich last year w...
