Which RCA driver you use? RCA had a few drivers the pre and after war. I am familiar with a few after war drivers that I tried in my 330Hz horn and I was not impressed. Reportedly the pre-war MI-1428B shall be the one to play with; I did not have thi...

I spent some of yesterday listening to the 8th and 9th from this set.
Recorded in mono by RCA in the early 50's I really like these performances. As a bonus the recording quality is good too. Does anyone else know them?...

Interesting, at this stage it's early in your testing so I am mostly interested in how they are terminated. Can you provide a picture of how the fluid tubes are sealed and the cable terminated to RCA?

This morning I went to MIT Electronics Fleamarket and found something quite fascinating: the RCA made sockets that fit 6C33C. I use Johnson’s sockets (I believe 273-275) that although are more expensive but they hold the 6C33C’s pins horizontally and...

Chris, I do not do “service” to anybody. I said what I said and what I feel
I do not use phenolics in MF and as I understand nether Steve Schell. In fact I do not think that it would be a good choose for MF driver. The carbon fiber from my poi...

Saturntube, thanks for the explanation. I thought that HR2 was just inspired by RCA but it look like it direct copy of it.

Without wishing to open a can of worms....Mine are the 1443 - same as the 1428B save for the field coil voltage. I've finally got round to ins talling some of Cogent's replacement diaphragms to restore them properly. I can't say enough good thing...

This record survived my college days, but I thought I'd lost it along the way. How nice to find it and hear it again, after so many years.The tracks from this LP were dubbed from recordings made in 1926, 7 & 8, presumably originally di...

In fact I posted a question to Wolf and he replied that he can produce the coil of any voltage the customer would like to have. That is good. The below is data by Wolf von Langa:
MI-1428 - original version of the RCA 1428 - especially made for...

If the RCA 1443 the same as 1428B but without the field coil then it might be even more interesting than 1428B. As I understand that those prewar driver had phenolic diaphragms that generally shall have tendency to be a bit soft with low order filter...

[quote user="jessie.dazzle"] "Short the ML2’s inputs and the hiss should be gone"
I assume it is not a mistake, and that you mean short the unused input on each POWER AMP (as opposed to the PREAMP).

Yep, I fixed it. If does sound very good now, exactly how it has to be. It turns out that my suspicion were correct: my Micro’s fat cable has died on me. I absolutely assure you that no one would believe that a regular phono cable able to introd...

Hm, this is what I am playing how: the new 18-cell and S3. I run it from a full time Milq and use it with no filter of any kid. Rony is right the depth effect is there, it is not even depth but rather multi-dimensionality. Indeed very pleasant feelin...

In the thread “Vitavox S2 with Electromagnets.” there was plenty of discussion about RCA 1428 driver. Here is more to it: the Great Vintage Loudspeakers made a new production of the RCA 1428 driver.
