55W all-tube amplifier manufactured in the 70's:
- Two-channel spars with a volume, an EQ bass / treble on each, a sharp boost, a serious boost. There is one between Normal and Bright on each channel, or 4 in total.
- 2 prampli lamps, a lamp shiffter phase, two power tubes, a light recovery.
- 2 outputs for HP to 16 ohms.


3 buttons with no decision-head, and then it sounds good right now ... it's ampeg.
No manual, but everything is simple, and there is a Schematic of the carcass mtallique al. The tricky point is output as 16ohms speakers are often 8 although it works well.


I love, well it's been two weeks that I have but seen as it sounds I never tire.
The power is not standard, and it allows to push just a little into a corner. Like that was the volume, and the beginning of the saturation of the lamps. I never heard that elsewhere. The sound is bold lightweight but warm, with a grain, but not pete mdiums Submitted testicle like other head! Waoo! You have to play even when I think of rock ...

I tried with a stingray and a Jazzbass, ca cash without any problem and it sounds again and again.

I plug in a 4 * 10 Ampeg or a peavey 4 * 10, the grain is, but it lacks a little low. I think I have a tent with 15 ', knowing that the baffle ddi this head is normally a 2 * 15. HP is a story of that anyway, I had the same problem with a heads transistors! Finally enough to spit ca rpeter but if it is only 55W.


The lamps light orange and blue when playing is beautiful! In addition it is downright beautiful (ah ... the vintage)
I tried a lot of head transistor (Ampeg, Hartke, trace, H & K, peavey), but what good blah. The lamp has a grain ca! Of course you must like it. The sound is frankly typical vintage. A must try if you do not know the color because it is a type of amplifier that colors the sound (and beautifully), and not transcriptionist excatement the bass sound like most heads. Warning!

Last point. It is much more expensive than the argus 380 (mine 750). Why? It's almost a head found in Europe, who has 30 years, which is home ampeg and more, and that sounds good magic!

Well I'll be back in a few months to tell you if I'm still happy.
