| Is a KT-77 a plug in for a KT-88? The first check of course is the pinout, and they match.In terms of operating points, the KT-77 is pretty robust (design max plate voltage = 800VDC, design max screen voltage = 600VDC). It's doubtful that your KT-88 amp was designed such that it... | |
| Premium distilled water for ultrasonic record cleaner And there's your answer (simple distilled).Cheers,Thom @ Galibier | |
| Premium distilled water for ultrasonic record cleaner I hate to rain impure water on this parade, but I have to ask the following question:If you go for lab or reagent grade water in the context of an ultrasonic RCM, will it be lab/reagent grade after the first record is cleaned (even if you pre-clea... | |
| Phono pre "Break-In" process? Necessary? TLDR (too long, didn't read) ...I don't know if it was mentioned yet but one of the biggest "break-in offenders" is capacitors. Some Teflon caps are notorious for taking multiple hundreds of hours and they go through weird stages along the way. ... | |
| Spindle Holes The RIAA specification is .284 to .287 (technically, specified as .286 +.001/-.002).Whether manufacturers hold to this, as well as of course the need for cleaning out the hole, is a case by case situation.As ttweights said, a .286 drill bit will w... | |
| Graham Supreme 10 inch mounting Greetings,From e-mails with Bob (and 10" armboards produced for my Galibier customers), the 10" arm is:Eff length: 247.000mm, p-s 230.283mm.If you use 248mm effective length, then the correct BAERWAALD p-s is 231.356mm.I take it down to 3 decimal ... | |
| Has anyone else heard Modwright PH150 Phono Stage? First off ... <<DISCLAIMER >> I know and like Dan Wright.I took a PH-150 phono stage home after the Rocky Mountain Audiofest, to evaluate and comment on it for him.Executive summary:Beautifully designed with first-class manufacturing t... | |
| Best Used Phono preamp around $2500 The saga continues. As I mentioned above, I’ve been playing with interconnects. They are in general, very low capacitance (about 15pF per foot). The one lagging item has been the shielded IC between the step-up transformer and the input to the ... | |
| Best Used Phono preamp around $2500 Update - post Audiofest (06-Oct).A lot of updates to the system over the past 4 months: (1) the new NiWatt amplifiers, (2) the pre-production prototype of the Eiger rim drive turntable, and (3) all new cabling (some litz cables I'm developing).Al... | |
| Best Used Phono preamp around $2500 One thing that gets overlooked in the Heron is how good its MM stage is. In my experience, the MC stage has too much of an s-s signature. Others will no doubt differ, but even when viewed as an MM stage, it's a great value. I run my Heron into ... | |
| Micro Seiki MA 505 Arm - how good is it? Yes Pryso. The Mk III has a straight removable arm tube (headshell is fixed). A point of clarification on the "no man's land" of tonearms between the $5-800 price-point and $5K and upwards.1. I haven't tried every tonearm extant.2. I intentionally... | |
| Micro Seiki MA 505 Arm - how good is it? The The MA-505 Mk-III does *not* have adjustable azimuth. The Mk-I (with its "S" shaped wand and removable headshell) does. I have not handled the Mk-II.Cheers,Thom @ Galibier | |
| Micro Seiki MA 505 Arm - how good is it? The 505 (in all three incarnations) was the baby brother of the MAX-237/283.It was a nice arm. I have a marginal preference for the Fidelity Research FR-64FX, but 10 different people could easily split their preferences for these two tonearms 50/5... | |
| Upgrade for users of 1/2" mylar belt Update - as I feared, these individual queries are not exactly the business model Blue Lake had envisioned - same with the other suppliers. I'm going to update the overview on my belts section to reflect this.Also, I'm going to put out a newslette... | |
| Maintenance for arms with detachable headshells I'd flush it with De-oxit and then forget about it ;-)Cheers,Thom @ Galibier |
