Wich melquiade?
fiogf49gjkf0d
Hi!

English's not my mother language so I'd have advices to choose wich Melquiade could be the best for me...I read that there's a lot of different versions...and I wasn't able to email Romy because of the robot barrier.

I've very good 95db Fullrange BR loudspeakers you can see below:

My cdp, a full modded one has got about 3v output/300ohms (lundhal opts)

My "preamp" is a no gain one: NPass B1 Buffer

My actual amp, is a 6wpc DIY PP class A without feedback wich is surprisingly sufficient with its little power.

In the bottom, and under 60hz, a velodyne active subwoofer, sustain bass frequencies.

I read in the Romy advices that a SE with "half" 6c33 sounded better than full 6c33 se.
Do I have to understand that the melquiade is about 8wpc? Is it a good idea to parallel "half" 6c33 to have same power as a full one with a better sound?

What kind of melquiade would be the perfect match for me?

Thanks a lot/David

There is no different Melquides versions.

David, there are no different Melquides versions.  Melquides is all about to use two-stage solution around cathode-ground 5E6P/6E6P with grid resistor bias where the bias voltage buffered by gas tubes. You can creates countless versions around this idea, from driving direct, low power tubes, high power tubes or even SS output stage but it will be still the same Melquides. The driver stage is the Melquides key; the 6C33 that I use at most of my channels was just my way to adopt Melquides.

I am not sure what you ask. If you ask about use full 6c33 vs. half 6c33 then… what difference it makes to you? You make the same amp and only disconnect one heater if you would like to. I do think that it would be silly to design the amp to use ONLY one heater. If you drive 6c33 then have a transformer and PS that will be able to care it with both heaters/anodes. If you chose to use juts one heater/anode then you have just a bit too overbuilt PS that never hurt and a transformer with more gap current reserve – which is also not so bad.

Regarding, your use of Melquides for your speakers or your preference to sound – I have no idea and I never sound issue such recommendation. I am not in the business of determine what would be “perfect match for you”. You might read the following advise that might help you.
