Hi KD1SH -

Am considering getting the 223 as an upgrade to my Symetrix 528e/Inovonics 222 combo. The thing that bothers me about my present setup is that I can't get the audio highs I want.  I crank up the highs on the Symetrix as far they'll go but the peak limiter in the 222 knocks them down again.  Since the peak limiter in the 223 follows its EQ block, I'm guessing the same will happen in the 223.  Or perhaps the knockdown is not so severe?  Would appreciate any feedback on this.

73, Rod KQ6F

There is information in this new article I did not know and there are photos of the production which I'm pretty sure are not on the Western Electric.com website.

Old tube news. Tongue

That has been 'discovered' several times in the last few years.

I seem to remember he was suppose to start making 12AX7's sometime back around 2007. Still waiting.

Given the current prices for the 300B's he manufactures, I wouldn't expect any additional tube models he manufactures will be "low price" and comparable to typical Ebay or flea market prices.

Everyone by now probably has heard of the production re-start of the Western Electric 300B triode a few years ago; now moved to a facility in Rossville Georgia, just across the line from
Chattanooga Tennessee.

An updated story was published in Wired.com earlier this week by Roy Furchgott on Charles Whitener and the Western Electric tube production which includes plans to add more types into production.

You'll have to bear with the damn subscription request hijacking, refresh the tab/webpage:

Enjoy,

I'm looking for anyone who may be going to NearFest and return through PA on the return trip. Or possibly will be attending Kutztown in May. I need some Pony Express service.

Mike:

OK, let me know what delivery method you would like.

For one of my HRO-60's I have solid-stated the HV rectifier, removed the audio 6V6's, clip-leaded from the top of the limiter pot to a 100k resistor then a 1uf mylar capacitor. This feed the instrument (hi-z) input of a tabletop powered speaker similar to a Fostex 6301. The audio is cleaner, louder and with more headroom.

I also reduced the rear chassis fuse from 2A to 1A to help save the power transformer. On another HRO I added a 1/4a fuse from the HV secondary center tap to ground.

Didn't there used to be a fellow in Texas that sold WWII military connectors?
