Default Power...

Hey Frank,

Hum, 2 PP El34's...is that enough power? I would have to say yes, unless you have something up your sleave. Now the question (as I sip on my morning coffee) is, should I even ask...yes I should.

Ok Frank, I'll ask...why, what do you have in mind?

Default WHAT IS WAS THINKING

Hi,

Well, I was thinking about a multiple PP of El34s but we better forget about it.

When I think I run a pair of self-made bookshelf speakers with a set of 2A3s PSE putting out a couple of Watts to more than satisfying levels....

No,I thought also that you could add a volumecontrol at the input
with a bypass connection straight in.
So for CD you could connect to that and for sources requiring a preamp you could then use the direct connection.

After all it is easier and less costly to drive speaker cable of some length than to use long interconnects.

Cheers,

Dave,

Please keep us informed on your vacuum-state EL-34 project. I gathered the parts to build one but got distracted. Have you heard a built unit? It looks like it could be something special.

Default MISSING PARTS

Hi,

Not much is missing really.

Add the CCS and you're there.After all it would work without it or have I missed out on something?

Cherio,

I haven't heard one, Dice45 has heard one that would be close. I have a number of other amps that are also candidates for this treatment. The 1st one out the gate will probably be a Scott LK48 with EL84s.

Default SMALL TELETUBES...

Hi,

A ccs treated EL84?

Sound like breakfast in bed to me.

Of the small power tubes I must say I prefer the EL84 over a lot of them till you hear the EL86.

Shear magic...

Ciao,

I'm hoping so. If the 1st one works out, i have Dyna iron for a set of monoblocs.

I haven't run across this one yet... have you heard the SV83?

Yes I have toyed with that one.
It isn't bad at all but i still prefer the NOS E84L/7320 made by Siemens.

The russian E84LM,the military one,is excellent as well if you want a bit more top end and speed.

The EL86/6CW5 requires a different OPT but can really sound impressive.
An excellent noval power tube.

Ciao,

Got any "maps" in your collection? From what i could quickly gather this would use an OPT in the same general impedance range as a 2A3?

Default EL86

Hello,

Most of what I found are Philips designs,OTL for a 800 Ohm speaker.

Naturally an OPT could be used for 16-8-4 Ohm impedances.

I've owned an OTL amp like that and much to my surprise it did drive my 8 Ohm speaker very well.

DATASHEET

INTERESTING STUFF FOR ALL OF US

AN ITALIAN SITE I OFTEN USE (PROTECTED ZONE)

And there must be more I could dig up....


I've seen prices on this tube from 5.00USD to 20.00USD depending on sources and manufacturer.

Cheers,
