I think these two models are fundamentally different as they are different in capacity. Naturally the Leak tl50 is 50 watts and is stronger than the Leak tl25. In terms of sound I don't see any difference. If I use it for a 20 watt coaxial speaker yo...

Romy,
Forgot to mention... The same people also offer a stepper-motor-actuated version, making it possible to do what you suggested above.
See it here (Scroll down to "Actuated Metering Valve") :

Dear Romy,
I have been reading the threads on GoodSoundClub about your journey with development of the Melquiades and Super Melquiades amplifiers. They are very interesting to me. I am pleased that your purpose was to produce a particula...

Romy,
Ok... I tried it... I backed off the screws securing the rear cover on one of the S2s I use with a pair of 180Hz horns. I backed off each screw a total of two turns, leaving a gap of 1.5mm.
I also did some measuring, and had left a 400Hz ...

Grid leak bias is not reliable itself . Grid current is very low and grid resistor is very big , the circuit become very sensitive to all destabilizing factors - capacitor leak , humidity , temperature . And when we apply a big input signal to t...

Romy, Big thanks for your answers. But i've got another question :)You mentioned gas regulator as grid current "absorber".Very good point, because personally i hate to use resistor as a grid leak.Instead of it i'll use choke - almost with any tube, i...

I have just taken out of my system a First Watt F5 clone Tim Rawson amp, It was substituted by a Telefunken PP amp with 6AQ5 tubes. Let me to explain.
My system consists of 6 way horn loaded speakers. I have a round Tactrix...

Ok, I ordered this a day before making the thread, and got them yesterday. These are overall the best headphones I've used, having neutrality, details, and natural sound. What's important to note is that when you touch the back or inside, you don't r...

On the line stage I currently use I haven't got around to fitting a selector switch so I really do have to change the cabling arrangement each time I want to listen to a different source. As I only really use 2 sources and occasionally an fm tuner wi...

[quote user="be"]ml8, could you tell what voltage and anode load you used the 6s45p without bias? What about grid stopper, etc.?[/quote]Kinda of 100-110 V on a plate. I didn't measure current cause by looking at curves i was confident that i'm not ov...

Maybe there is no difference when you take a Leak... An amplifier can only be viewed in the context of the complete system. Watts say nothing about sound and capacity is relative.In any case, if you are looking for your own system, the amplifier mode...

[quote user="Saturntube"] The difference soundwise in this half range 180hz and up horn module between the Leak TL12.1 amps and the First watt F5 clone was big, mainly the tonal balance is very different with the midrange sounding thin. Highs w...

romy, there is a tuna freak in los angeles who insists that the only way to get the best sound from the l-02t is to use kenwood's proprietary cabling. i dunno, i have never tried one. i have tried two earlier analog kenwoods; my experienc...

Hi Romy,Due in part to your enthusiasm for the older 78 rpm recordings and in part to my own curiosity I have decided to add the facility to play these to my system. It also helps that an old aunt has given me a large quantity of classical recordings...

Hi Romy,Can you describe how your vinyl playback and conventional CD playback fall short of what you are getting from FM? Is the FM playback of 'non live' material still sounding better than your vinyl and cd? Have you tried recording vinyl wit...

Romy, you specifically mentioned Shindo, and this is a well-known example of the "Old Parts School" that seems to be able to channel It. Examples I have heard have all been simpler Music via simpler speakers, so I don't know how it works with big sym...

Romy, it is rare for Alinco magnets to drop a charge "just like that", although time and/or physical shocks can diminish the magnetism considerably. If you happen to know how much charge your drivers started out with, then you already know more than...

Of course I haven't compared it with the Sansui, which appears to be a very serious machine but the Leak sounds more natural to me than the other highly regarded tuners available over here (in the UK) such as the various Naim models, the Audiola...

...but resistor between screen grid and plate, to my hearing, makes sound slightly unnatural, especially in highs.But this may be not true in your case (i didn't try to use this resistor with 6E5P, only with other power tetrodes), so i think i'll sug...

[quote user="peter foster"] My understanding had been that biasing method is a method of setting up a given tube so it works with the wanted anode current at idle with the wanted anode voltage and these conditions are met by somehow applying a correc...

Congratulations on the build! anthony wrote: Yours uses all toroids, or mostly so, which are more efficient than the EI that I use.
Why have you chosen EI vs toroids? The latter emit less.
Cheers,

Both of these short excerpts sound very natural from what I can hear on my PC's speakers. I'll have to burn them onto a cd and see if I can coax the sniffy Teac into playing it!What's the position with regard to this (or any other) material that...

In our experiments, the more power we threw at the A7s, the better they worked. I heard some of the original "theater" version Altecs playing with their original "dedicated" Altec amps, and these sounded considerably better; but I never got ahol...
