2 pill amplifiers...

[Oatmeal]

I'd like to know something about these 2 different size 2 pill amps...
One has the 2290's in it.....the other has 2879's in it...

I want to know, what kinds and size tube amps can these amps be used with for a driver ?..

 

[9C1Driver]

What brand or name amplifiers are they? Reason being there are big differences, palomar, texas star, x-force, and then different classes. Would it be best to drive a tube amp with another smaller tube amp?

A 2 pill like to try a DM or maybe a BM Technology amp...
Kinda doubt it been a XF amp..

Or maybe a JB 12 or 15 modulator...
Used to run a JB 12 years ago..

I personally dont like to drive an amp with another amp. I would go with a high powered radio to "drive" a HD amp. Maybe a 1-pill though.

Whats the difference?

Whats the difference?

Stability. Less chance of over-driving. Better control of power. Less mess connecting things up. Less chance of things going wrong. Generally lower power consumption.

1)Stability. How is an outboard amp more stable than an inboard amp?

2)Less chance of over-driving. That's operator error.

3)Better control of power. See#2

4)Less mess connecting things up. See#2

5)Less chance of things going wrong. See#2

6)Generally lower power consumption. I can't see that personally.

I did the high power radio thing a few years ago, an external driver is a lot more flexible in my opinion.

More tuned circuits interacting in the presence of upset impedances or RF fields. More common that you may think.

True but nevertheless a consideration. You asked how it was different. this takes that issue out of the mix.

6)Generally lower power consumption. I can't see that personally.

You can't. I can. Add up all the stages and efficiencies and how much TOTAL power is being generated to produce that final output number and see.

I always thought that driving a big amp with a high powered radio reduced potential impedance mismatches that could occur when running 1 amp into another amp.... maybe I'm wrong in my thinking, but that's kind of a rule I've always lived by.

So many different opinions. I guess the old saying is true. "More than one way to skin a cat.".

I've always wondered how many ways there was to skin a cat......:laugh:

 

[loosecannon]

sure, there are more than one way to skin a cat, but there is only one way to scrub a cheese grater.

anyway, to put it another way- linear amplifiers do not like to be connected to coaxial cables.

If you was going to buy a 2 pill and later use it for a driver, would you buy one with the variable power in it ?...

 

[dx31353]

Yes.

10-4, what are some advantages of having the variable in a amp ?....
