3 weeks, eh? Vs. how many years for functional DSET? Next, a great 5 cent cigar!Same questions about decoupling a phono stage from the split, re-setting the output impedance, and doubling the output. Where and exactly how does one split and boost the...

Hi Guy, I know what you mean; this phono stage really should not work well at all. I mean, voltage doubler, 3 stages of 12ax7, feedback, cathode followers, garbage looking power supply shared tubes for stereo...mortifying isn't it! These ...

Yes, 10 uF is rather large for a coupler, alright, but not unheard of. Conversely, .47uF would be on the small side for a "powerful" amp using the 6C33C out (4.7 uF might be more like it...). My own phono stage uses 5 uF film couplers. One would supp...

Thanks for the comments Romy. Would appreciate pointing out where the schematic is for the 7788 phono preamp or even better your friend´s 7788 mic preamp schematic. I can use the phono stage circuit minus the RIAA as a starter and th...

I think that any line level tube stage can be every much of an expressive tool as any other device in the chain. I am also not sure that the biggest difference between digital and analog is the sampling process.How "transparent" is a cutting lathe or...

Romy Hi, there is nothing to say really, I was trudging up the usual hifi route, ( B&W 800's usual high powered solid state amps ) I thought a turntable upgrade would be the last step! Went to GT Audio to listen to Thomas Woschnicks tur...

I would not say the circuit (per se) was becoming more sensitive to tube choice (and neither would I claim it's not...); I would say that as I have developed the system I have been better and better able to hear what more and more piec...

Hello Romy
This is my first post. Did you take courses in electronics and mechanical engineering or have you learned yourself outside of a structured environment? I am very interested to become proficient in working on/modifying my own electronics. ...

Hello, this is my first post here - this is a wonderful web site, critical and fair - a lot of knowledge here and i consider you real connoiseurs - that's why i'm hoping to resolve my problem here.
I have a Micro Seiki SX-111FVL - the big L one, a...

Hi, [quote user="Chirag"]103 or 103R + mass loaded SME headshell + 3012 or a 3009 + Seiki 1500 + hagerman opamp phono stage (good only with select parts and battery power) or an EAR 834 (with some mods) and some old...

Hi Guy, [quote user="guy sergeant"]My experience with the 834p stemmed from having one at home for about a year soon after it was launched. I did try different types of ECC83 in it which did change it's balance slightly but not enough to make me like...

I agree with your observations, and my own misgivings swirl around exactly the points you raise. In addition, I have tried battery phono stage and all it had to offer was quieter "background", everything else was worse, despite the wild and exo...

I guess Thorsten is laughing since he should be the main receiver of TdP email. Popularity of a product is a double bladed sword. I do hope that sales of EAR 834 phono stage increased notably after Romy decided to make that circuit into his "end of ...

It has been 1 year since I started working with the ML2s with all new tubes installed. The ML2s have been, by far, the biggest step I have taken in hi-fi in 45 years, and the "upgrades" I have done since the ML2s have necessarily been in a...

if they don't try something first and report back on occasion?I finally ran out of patience and tried the damn automotive dielectric grease myself on the pins of 4 new tubes I just put in the Lamms. I also for the first time and again...

I have been running my nominally 8 Ohm speakers from the ML2s' 4 Ohm taps for quite a while, in order to keep the sound from getting squirrilly and to keep the bass strong enough.Today I used the re-capped/improved K&K phonostage as a source and ...

In impatient, ill-advised. manic efforts to "compensate" for the EFFECTS of bad power I have swapped ICs, used different output taps, re-configured grounds, swapped tubes, re-positioned speakers, adjusted VTA, messed with my BR ports. And ...

This report is on a new pair of Marantz MA-9S2s, following up on the relevant post in the "Powerful Amplifiers" thread. I installed the amps in my usual stereo set-up, to make it easier to draw a bead on them. I still have less than 100 hours on th...

Apparently it still happens: good electricity during the day. Wifey went to the fair with a granddaughter, so I took full advantage! If forced to guess why the electricity was good, I'd guess that the nearby school is out, kids are visiting relativ...

No telling anymore how good these amps can get. Today the re-configured phono stage finally "burned in" and I used the ML2s for almost 5 hours. Although I have read that they keep improving as you use them, I was not really...

Sorry, I should have said by now that my (15" Audax PR380M) bass units are FLAT to 38 Hz, and then they roll off naturally at 24 dB below that, meaning if I have 38 Hz @ 100 dB, then ~30 Hz is still >88 dB, and obviously 20 Hz is still p...

I've spent two more nights examining and fighting my ham (I'm vegetarian and I want my phono to be so as well).1) I did Romy's excercise with shorting the stages via a 0.47u cap to GND. Shorting the plate of V2/grid of V3 resultedin the biggest reduc...

In your earlier piece about how to use the S2 'properly' you wrote"Whatever happens between the 400 and 2,5 is pretty much unnecessary for you garbage. So, get any known to you soft capacitor of 3uF and place it in series with the S2 driver. This wil...

I have a preference for making the power supply a certain way and using certain types of components. If I do that and am consistent about it, I can get better results from some of those old tubes than I can from the more recent types. But hearing one...

I don't know this Steve Klein. I don't know what bullshit he uses to sell Audio Note's products in the US. If that is what you are attempting to satirise then fine.I am quite familiar with Audio Note Japan's (Kondo) products. I don't use any at the m...
