[quote user="montepilot"]How would modifying preamp affect sonic character other than just providing more gain. What's the advantage? Once such a modification is made are you restricted to using the 6E6P-DR tube only? Will it change the sound o...

Merlin, I have nothing against Bernings, in fact I found it all educational as I never had exposure to them. Well, perhaps I did hear them at some kind of hi-fi show but just did not paid attention. I hardly believe that I will hear Bernings as I’m l...

I was looking at my recent observation that smaller anode makes better HF sound; better intimacy of sound and better articulation of detains.

Spending some time listening carefully my new setup after fine-calibration I recognize some inaccuracies in my previous comments and some mistakes of my original objectives. Here are some observations I would like to make. If some of my observati...

Jessie, you know it is sometimes disgusting to read your posts. In some cases you write posts that are one to one with what I would write and if not correct spelling then I would swear that it was written by me. A few days back, talking with a gu...

[quote user="floobydust"] Romy,
As you're planning to run a 6K load, you can run less current without the transfer curve suffering as much. So, another shot at some numbers.... rather than use a RC setup to drop the voltage, Hammond (not my fa...

[quote user="JJ
Triode"]I'm not sure if the Salamander-style rack (wooden shelves
supported by nuts and washers on threaded rods) will support 800 pounds, but if
you put heavier items near the bottom then a wide heavy-duty version might be
fine.[...

Following my recent “new objectives” with tweeters (partially covered in the last posts of the following thread)

[quote user="drdna"]After seeing the variation in the sound of the TU-X1 to the quality of electricity, and thinking about recent discussions about the Direct Heated Triode, I would like to start a compendium of anecdotal observations of the idiosync...

I am interested that Romy has found some interest in DHT amplifiers.
Many, many amp builders have used many, many tubes over the years, including many IHTs, triode-wired pentodes, etc. Japanese builders have used big transmitting pentodes driven i...

[quote user="KOTriode"] The Melquiades give me inspiration to build this 6C33C amplifier. It's on a stereo chassis that has few unique features - Vacuum tube rectifier separately for Input/Driver and Output tubes. - Regulator using the same tube ...

[quote user="drdna"] The altered topology of DSET has the potential to have disadvantages. There is increased overall system complexity and this often seems to be a negative. Beyond this, it is difficult to expound, for me, on the specifi...

[quote user="Chirag"] It seems the 6e5p is driving the transformer directly. I've used various versions of even simple mosfet followers to good effect at the headphone level, but never considered using a speaker level transformer. Did you and D...

I know – it idiotic even for my site but it us what it is. I do not think that I can generalize my observations as I have not a lot of experience with DHT tubes but one thing that I have been observing for the last week is really arouse my curios...

Well, I have to admit that I did not listen the whole sound of AC vs. DC filaments yet. I will bring home today my DC lab supply that I use for my electromagnet coil and will give the try. I still at this point am not concerned about the “whole ...

[quote user="floobydust"] One of the reasons I no longer use a tube tester. They make a measurement at a specific target operating point(s). You don't really know what it is, so what are the chances they will be close to your actual circuit opera...

Dear Romy, thank you so very much for mentioning our amplifier to your excellent forum. Indeed, during the last 5-6 years there are a lot of manufacturers “from non traditional hi-fi manufacturing countries”. In particular, in poor old Greece we ...

Meriln, this is one of the subjects that disturbs me in your description: your bring OTL consciousness to justify Berning and you bring all those foolish OTL people as witnesses to give credentials to Berning. We all know Doctor Gizmo and all know hi...

The 6C33C preamp? Hm, this is bold. As I see you use it as a single stage buffer with only one 6C33C and couple output with a transformer? I head the Germans built something like this but I never heard it or saw it. I do not feel a need for such ...

[quote user="floobydust"] Some very good points here... if I downloaded the correct schematic from your site for the 6-channel Melq amp (also has the term DSET in the title) then you have created a 6-channel SET amp with built-in crossover points. Yo...

[quote user="peter foster"] By "dynamic viscosity" do you mean the reluctance of an amplifier to be dynamic, i.e., the degree to which an amplifier sounds like it is bogged down, usually as a result of a poor rise time on transients, i.e., poor HF re...

[quote user="noviygera"]Romy,why do you feel the
SS amps will not provide as good bass as tube amp? Since there is such a big
selection of SS amps, also hybrid one, is it a general rule, regardless of amp
power and type? Is it the type of distorti...
