Yeah, I know, isn't it great ?

Tomatito · 30th October 2002, 07:39 PM

Actually, to make things worse, I got the 5692 for 50 dollars, a nos pair

Hi,

At 50USD each that is not even all that expensive.
I've seen prices at quite a bit more than that.

Trouble with stuff like this is what you're going to pay in a couple of years.

So better start saving,you're never want to go back to the regular stuff after the Red Octobers!

Oh well,

Hello Tomatito,

Very nice indeed. Thanks for the underside pic. I am the one who emailed you earlier this month about your meter you have installed in your amp. Glad you joined this board. There, as far as I know, are two of us who are currently working on the JE labs 300b amp, Ciscokid and myself. CK is alot further along than myself. Anyway, don't hesitate to chime in when I post a question, I will need a lot of serious, thoughtful, insightful and humorus help in the very near future.

Hi Paul,

I hope I will be able to help in any way. I 'm not much of an expert myself, although I've learned a lot during the process of building this amp.

Very good job!

I would put a copper plate over the chassis for the looks.
look at my amp.

Regarding the hum issue,do you have dc filament in the 300b?

I have a AudioNote kit one, and hum is there also. I think these babies can't live without some hum.

Is it audible when music is on? In my setup I can only hear it in the tweeters at total silence.

Thanks. The 300B heaters are AC. Only as a last resort would I try DC. First I want to try Steve Bench's trick : http://members.aol.com/sbench/humbal.html .Anyone try this ?
