The truth about my amps.....?

The stealth was even worse.

On the stealth the front end gain tube was also used as an ultra high impedance

preamp output. In other words it sucked bigtime. Could not even drive 3 feet

of cable. So ray learned from his serious mistakes, and on the B52 added a

simple cathode follower.

Wow, that's taking stupid to a new level. So with a 12AX7 on the input the stealth would have an output impedance of something like 40k or more, and with a 12AU7 it would be around 1/10th of that? I didn't think it was possible for a "designer" to be that incompetant.

This is ray we are talking about here....

His stupidity is only matched by is arrogance...

With a 12au7 the output impedance of the preamp section would be about 18k.

With a 12ax7 it would be closer to 25k.

Output impedance of the conrad johnson art preamp (act2) is specified as <500 ohms

ct5 and ct6 are 800 ohms

Ray's B52 is something in the range of 1500 to 1800 ohms.

Wait, I'm rational, informed, and intelligent? >:D

Judging from what you say and own, I'm taking it that you are at least informed and intelligent. As for rationality, there are many forms. Though you may not consider yourself to be rational in certain aspects, you are at least rational in way some individuals such as Mr. Rose are not.

What is to discuss. An opamp, and 2 transistors. Exact circuit published on headwize 2 years before

ray built the piece of shit. I have discussed this plenty, do a search. And the Apache, you guessed it

is 2 x hr2 in one box. Virtually identical to the circuitry in the headroom products circa 2000 or so.

Nowhere near the beef necessary to truely drive low impedance headphones.

Oodles and Gobs of feedback. Yuuch.

I'm feeling fine billy. :P

Still happy from massive hunk of moo from mortons on saturday.

Combined with huge shrimp alexander.

Been working on a failed drive in a 3T raid set since friday. Started friday morning

and just finished about 15 minutes ago. Sure would like to find a way to back that

thing up in less than 1 week. (removable media)

At least the hr-2 is built well with none of rays famous major errors.

1) It can't cook eggs on the top panel.

2) No noise from the switchers because there aren't any.

3) No mother fucking huge caps that do absolutely nothing.

On the other hand

1) not only is is not pure class A, it can dip into real class B due to

layout error with temperature compensation diodes. (fixed in apache)

Ok, go and look the rest up. I need coffee!

There billy, you happy now...

IBM would be glad to sell you a tape backup solution that could EASILY back up 3T a day.

And eat up 1000 sq feet, and consume HOW MUCH POWER.

OK, that is not quite fair, an EMC box will do it in 4 rack panels.

One on line raid'd and mirrored set, One off line set that runs

the backup on 5 or more 600gb dlt drive in parallel. Then it

would only take about 6 hours. Plus robots and stacks of tapes.

Price is still nasty.

Want something that sits on a desk, makes no noise, and can do

at least 200 GB /hour. Without changing tapes!
