Roman,[quote user="Romy the Cat"]May I ask you, this realization of yours… dose it has any “sound”. [/quote]The one we have build which is a little different (6S45 not C3g, also tried WE 417A, 437A, TX-101 Copper not silver, AN UK Line Output Transfo...

[quote user="Paul S"]Romy, no doubt the following derives wholly from my ignorance on the subject, but I have not been able to get away from a sense of "variable compression" with any compression horns I have tried. By "variable compression" I ...

I would like to expose what my intentions are what I was tiling above about Goto 555 or a similar 200Hz driver. My S2 does not stress the bottom of my 183Hz horn. My multi-cell is expositional and those types of horns do pick honk very aggressively ...

[quote user="Romy the Cat"]Joaco, thanks for sharing. You said that you use 2A3/45 amplifier, do you use choke or capacitance right after your rectifiers? It would be interesting if you plug a scope into your loaded regenerator and post a picture (ma...

I've been pushing this intellectual excersise (masturbation?) of solving Romy's constraints on a powerfull bass SE amp.Thanks to Stephie Bee the humanity have now a decent model of GU81M, so before electro-cuttingonself, one can see if the electrocut...

[quote user="nl"] Gordon Rankin of Wavelength Audio did a series of one-stage DHTs with a step-up transformer input about ten years ago. I think they were called the Mercury series. By all accounts, they sounded good, but of course had limited gain, ...

Thank you for your answer.If I understand well, In purpose to do something realistic and good sounding. I should use at least 2 amplifiers (one for high frequencies and the GM-100 amp for low frequencies) with a tubes active filter at the inputs of e...

I figured out that that after I choke Thomas will be too
bored to live at family forest lake and to listen my records in solitude – he would
need a company. So, today, The August 23, Thomas’ brother and sister: Charlie

[quote user="Antonio J."] but the builder thinks that performance wise it's better to use several smaller caps paralleled [/quote]
If he thinks this way then let him to do whatever he wishes. Still, I assure you that Sound of the Milq dose not deriv...

Without regulation, this amp would not work correctly due to its design: DC coupled and fixed bias. The high transconductance will make the bias current varied as much as 50-100ma due power line fluctuation without the regulators. It mi...

The “Enjoy His Music” published the old celebrated by many DIYers Herb Reichert’s article about his 300B amp ideas.

Romy, do you power your End of Life phono from the PP??
I have the same phono, with choke input PS for both the heating and the HV.
1) If I plug the phono just to the wall, the noise just normal wi...

This evening I took myself to performing additional tests with the entire system completely disconnected from utility ground. Following Romy's considerations about different grounds, and Richard's absolute belief in the capacity of a properly working...

CV, Good scenario as well but my leading idea is slightly different. I would like to keep any reactance from the path, would it be inductive of capacitive, to assure ultra fast response time. Basically I would like to maintain the MF amp as it used ...

[quote user="Romy the Cat"]Because GM70 can work in A2 class the ML3 has a very powerful high current-capable second stage (I do not know it they are 4 parallel 6H30 of some kind of composite follower) to be able to handle the GM70’s grid current.[/q...

...the problem starts outside North America - eventual shipping a faulty unit there and back, paying each time the cargo (20-40kg), customs, taxes, can be quite costly.
Romy, reading the beginning of the thread there seemed to b...

This weekend I found some transformers in my storage and I put together the Baby Melquiades headphone amplifier. It turns out to be very cure little amp. It is 9'x9' but has all Milq’s incidents including the choke intuit supply for plates and t...

Hi Roman
I'm slowly gathering parts to build your amp.
In my old email to you I've mentioned that I have a pair of monster transformers 310-0-310 2A .I'd like to use them as a main transformer for bi-tri amp configuration ,with input choke load and...

Thank You
I'll experiment with the PSU a little. The transformes have only 1 Ohm DCR
and total supply impedance for a channel would be ~ 45 Ohm (with two chokes in series) Imput choke looks like can take 1 A current!All Iron is mil quality and p...

Good concern, I had and have it as well. I do not have an answer at this point. It should be stressed that my description of artifact was just my specific description of THE artifact, the MF texture music had also a “face lift” - I just d...

I connected the loudspeaker to check if the music was flowing from it. The amplifier works !!! I hear the music!!!
I'm exhausted.
Now it's evening at my place, I can hear the rain outside. I think I'm going to do what I want...

Here is the signal box:The design is double mono past the VR's. Including the bias.
The coupling caps are Arcotronics KP172 from RS-Online, quite prised by Thorsten Loesch. THey are sitting on
sorbothane pads. The air caps are: 1) 365pF some +/- s...

The Super Melquiades Amplifier is essentially the 3 parallel running Melquiades amplifiers optimized for driving my Macondo Acoustic System, with line-level or inner-stage filters. This SET uses a full 6C33C at LF output and ½ of 6C33C for HF and MF ...

[quote user="Romy the Cat"] Well, I figured out – if digital is dead then I need to put the heavy artillery in the fight I begin to spin records. With my TT setup I have an interesting tool - I run my input-choke powered “End of the Life” Phonostage ...

I decided to make this post in this thread (you are at a second page of the thread) about the “second-type” phonostage. My needs for a Santa’s bring me a nice “second-type” phonostage really got stronger. If you remember my 7788-7721 tow stages,...

[quote user="hagtech"]Yes, steel chassis can be both good and bad. It likes to conduct magnetic fields, so you have to treat things appropriately. A little spacing under a choke can go a long way. Otherise you have a 120Hz motor.&nb...

I run both of my Reference and Daily tonearms into my “End of Life Phonostage”. As I told I do not know any way to commutate signals at phono level signal and I just re-plug the phono cables at the phonostage’s input. I have no problem with that ...
