Got today a party of the 6C18C from 1960s, an interesting tube. The plate looks like 1/4 times larger and has no bridge between the halves. The 6C18C has even less plate impedance than 6C33C and it appears that it futures inside more “colorful” metal...

I already wrote a few times at my site about 6C18C. Search if you are interested.

If you use the 6C33C for amplification or regulation then you would hardly avoid attention to 6C18C. It w...

Was talking with various audio people about the 6C33C I was amazed that people are so clueless about this tube. The people are so filled with some foolish prejudges and faulty notions about 6C33C that I deseeded to put together a brief “6C33C user ma...

[quote user="KOTriode"]Romy,I have good confidence that it was the tubes and not the circuit. I have checked the cathode driver that bias the 6C33C and there was not any problem. Sure if the cathode bias failed, the 6C33C current will shoot way u...

Since I got my stable and good quality electricity back I recalibrated my bass horn. Again, I set it up with very precisely and absolutely without any measurements, juts by ear, to sound exactly how I want it to sound. This is in a way my crown jewel...

What would I do if I move to a much larger room and the power of Milq’s full 6C33C would not be enough? Surely it would be possible to go for transmission tubes but they all high plate impedance and high voltage. If I parallel all my bass drivers and...

It turned out that I made my Melquiadenisation with 6C33C. Not practically because it is good or bad tube. The choose of 6C33C was partially accidental: in the beginning I was trying to make an amp that would be able to work in multi-app configuratio...

Morricab,
I do not know the “truth” and what I said are pure my speculations based upon what I hear and what I measure.
Yes, Lamm drivers at 310mA quite hard but do not forget that his objectives, besides everything, were to get out of his SET max ...

Here is the general specification for the parts that I used. The selection of the parts implies some liberty of course. It will be your amp after all, not mine - do whatever you wish. In some case when I feel that requirement is critical I will stres...
