[quote user="Romy the Cat"]When you are taking about “caps at higher frequencies”, then what do you
mean? The line level, the speaker level, the line level between? Do not forget
that a RL filter is always preferable over C filter.[/quote]It was re...

[quote user="Romy the Cat"]As much as caps in speaker
crossovers makes deference, so do they make in coupling applications. In Milq
the cap is light duty as the amp never goes A2 and the cap is not change the
polarity, still the coupling caps do m...

Romy, I understand that at some stage you trialled a number of different capacitors and settled upon Electrocube 950B/D not necessarily for the Melquiades but perhaps for some other project. I was wondering if you ever experimented with different co...

The fullrange Milq will be built in an oversized chassis with the intention of adding maybe two or more channels down the track and perhaps some line level crossovers. So I will up spec. the mains transformers so they can handle a larger draw and wi...

I talked to my friend for whom I will build the fullrange Milq and his response to the foot pedal question was "heck yeah"...so I will go the same way as you Romy. It is a fantastic idea and really quite simple to facilitate especially with that Mag...

Thanks Romy.Can you remember what caps you used in the HF filter? They are certainly not standard values and I do have a memory of you trialling air caps.I spent too much time today trying to figure out if I wanted a power switch for these amps and ...

So, looking at the schematic below......I have a few more questions25 turn pot in the filament supply. For the life of me I can't source a 25 turn pot. The 10 turn Bourns 3590 is the closest I can find. Do I need to keep looking for a more sensiti...

[quote user="Romy the Cat"]However,
if I did it again then I would not do it in context of multi-channel amplifier
but rather I would make a maket amplifier able would test my ideas with it. [/quote]While I do like the idea of experimenting with MF...

Thanks Romy.I have secured a couple of pair of YO186 and some 1940's Sylvania 45's to play with. I wish the YO186 were easier to come by but I think that I now have enough for me to get a very good idea of the capabilities of the tube and circuit, a...

Sorry Romy, I was not clear enough, but the resistor that I am questioning is in the Fundamentals Channel (not the MF Channel as I believe you referred to in your previous post) between the OPT and the S2....

resistor you run the S2 without any components between it and the OPT. .
Actually it is not a resistor connected...

Romy, thank-you for your help so far. Unfortunately I now have some more hopefully simple questions regarding the "pre-final" schematic from your "6 Channel
Melquiades" thread (see below). 1.
Do you have a “final version” of the
schematic any...

[quote user="Romy the Cat"]Make the full-range and then you will see where you are.
Still, I feel that for MF channels it is beneficial for do with a good DHT output
stage instead of 6C33C and perhaps it is a good idea to use DHT driver as well.
S...

[quote user="Romy the Cat"] That is very good approach in my view. The
problem is in this approach that you have to have high sensitively speakers
that you would be able to use with that test full-range Milq. The behavior of
the Full range Milq wi...

Hi Romy,
I am planning my own DSET build. I have based my speakers on your Macondo and
am busy turning MDF horns in my spare time.
Once that is over I will move onto amplifiers. I plan to build a fullrange Melquiades for a
friend and the...

[quote user="Jorge"]Romy,
Thank you for sharing the link!
The second part is better!

Romy, how do the YO-186's last? It would be nice to think that such an expensive tube lasts quite a long time. Have you had to ...

I had a look at the website and the AU stands for gold (from the periodic table) not Australia. Plus the prices are in pounds not dollars. Interesting turning them in walnut though and I agree totally about the "horns underwear" and industrial thre...

Thanks Romy.Just for anyone else reading this, Mike Harvey (vitavoxhifi) has given me the following information...There are two types of S2 diaphragms: pre May 1972 (aluminium type with paper former - fitted standard up to serial 4940 and for about t...

[quote user="jeff1225"]Yes Rommy I agree with most of your comments above. What I found interesting in the larger installation was the time alignment and the bass implementation. I do disagree with your statement of not stopping by to see the Hornfab...

[quote user="Romy the Cat"]Here is the list of the thing to do with Vitavox S2 in order to use it in 4-ways installations. The S2 must not be used in 2, 3 ways systems. It possible to do with S2 whatever you wish but pretty much any other way to util...

Glad I could be some small catalyst in part of your "amazing audio feelings" Romy. The world suddenly looked different to me when my first-born came along and there was a sudden readjustment period where I began to consider the relative importance o...

Romy, I appreciate that this is an old thread now and that you may not remember everything from your time developing these amplifiers, but I have a (hopefully) simple question about the upperbass crossover in the schematic above. All other channels ...
