Anthony,
I feel that 18AWG is a bit too
weak for the filaments. I usually use 12. I do not know if you allow to have
any ventilation around the 6C33C, I did. In my full range amp, I had holes around
the 6C33 panel.

Why not? Wilson for many years each 2-3 years updates own flagman. They had Grand Slamm’s number of revisions where they constantly change tweeters, other driver and resistors in crossovers, introducing new rounds of opportunities for the custome...

Dear Romy and all,
I’ve been lurking here for a few months and - after a sceptical start! - I have found this site an Invaluable Help. Many many thanks to Romy and all involved. My system is now starting to sing and make nice noises for the first ti...

The headphone amplifiers are mystery for me. Form one perspective it should be simple but from another perspective I never heard any interestingly performing headphones amplifiers. Well, I have to take it back probably as wherever I even heard differ...

If you think that I am not an idiot then read further. I have been looking at my Macondo calibration

[quote user="Romy the Cat"]Another this the I at this point has no idea why in my use

I think if such a woofer “ignites”

cost. To do “right” thing I would put pneumatic decompiled be...

As some of you know I’m playing last couple days with Red 10” Tannoys from 60s. My selection of 10” was not accidental -I would like to get as less as possible of that “Tannoy bass” but I did run very far the “Reds” turned out to have 27Hz open...

After fantasizing about an infinite baffle, I calculated what kind of structure I'd have to build (in lieu of an attic/crawlspace) and this is an obvious no-go. A more practical idea is a sealed box with two parallel ScanSpeaks per channel. This ...

I was rushing when I made the last post. Wanted to share a little more about my thought process and how I arrived at doing another large-scale masochistic audio project. Making a bass horn is a huge risk - the results can vary from exceeding expect...

I am in the think through stage of improving my playback. Each loudspeaker currently has 2x 12" woofers in a sealed 80 liter cabinet (Fc-500 Hz). Measured LF extension is more or less flat to 30-35 Hz. Efficiency is close to 100dB/watt. The list...

I’ve been harassing my horn-maker for quite a while with an idea to go for straight, no-cheating 45-50Hx horn. We discussed it countless times and sometime probably we would go for this, and particularly if I figure out how to resolve the delays prob...

Many people know that I run a side business doing wedding photography. During the 24 years that I have been doing the wedding gigs, and after over 950 jobs that I went through I kind of have seen all imaginable wedding bands. Certainly the “events mu...

Paul,
Thanks for pitching the Johnson capacitors. They do not look “large enough” for me. I used in past the following caps:

They have very good size to value ratio. The ironic part that I just called to th...

hello again Romy, cats, friends...

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...

I think the usage of Romys Injection Channel has misguided you to think it was implemented because of a certian lack of tone or some sterile sound, nothing of the sort, I cannot blame you for not having listened to Romys system, but theo...

I understand all disadvantages going digital.
I strongly believe that minimal influence to the signal is the most important aspect.
And influences in digital domain are usually terrible.
But I'm not sure what other options available....

Last night I built an large and ugly mumetal sarcophagus around the Dave Slagle’s choke and located it a bit aside from the location it was before. The efforts killed perhaps 98% of noise. I did not have good mumetal cans but I have .004 sheet of...

With exception to the fact that I have no bass my new room did not give me a lot that I feel might be qualified as strange. I still do not know this room as good as I knew my old room but I will be there, it is a derivative of time. It is not tha...

First of all this post is NOT related to the recent PP2000 problems but it has a border, general view.
The recent LX’s posts made me to think about the PP2000 buttery. He reports that his buttery got way weaken from 2009. I used my older PP200...

[quote user="Antonio J."] Regarding the C2 thing, He said that I misunderstood his proposal, what he says is using five double 200uF+200uF cans (400 uF each cap), which are rated for 500V (not 200 as I misunderstood) to get the 2000uF needed for C2, ...
