Ampeg PF issues cutting out?

[JimmyM]

Yea,it’s 150 watts. The Rumble is 140 but you get 200 with an external cab. No reason Ampeg couldn’t do the same, unless they weren’t capable of making more power out of a 1x15. Like the 210, it’s rated at 283 but you get 450 with an external cab. Should have done the same with the 115.

The BA210 and Rumble use lightweight class D heads if I'm not mistaken. The BA115 uses a trad SS amp. Making it put out more power would have significantly raised the weight. Now could they have made it with a class D amp and been fine? Probably. But on the bright side for you, the company that made that decision no longer owns Ampeg, so I guess we'll see what Yamaha does when they relaunch.

Soooo, Yamaha now owns Ampeg? Didn't know that. I can't imagine this being anything but great news for Ampeg and it's fans, Yamaha has done quite well for itself.

The entire BA series is SS, at least according to Ampeg (page 7 below). Thats probably another reason why I prefer the tone to the Rumble, which is class D.

My experience:

I bought a used PF350 years ago and it served well for 3 years until the day it was in a cold (32F ish) car trunk for about 6 hours before I brought it into a rehearsal.

It made distorted/quiet sounds and was unusable, then worked the next day at home. But ever since then it shuts down if driven too hard.

So they are not hardy as an old Peavey, but what is?

 

[Super Bass]

I think it's unfair to say this is similar to other amps. I haven't had this problem with any other amp I've owned or played over a long career.

Same with me... Only had Ampeg fail on me with a brand new V4B and a brand new SVT.

Were you aware that ALL class D power amps are solid state?

 

[mbell75]

Yep, but Class A/B is different than D now isn't it?

 

[JimmyM]

There are lightweight amps that are class AB as well. Micro VR, older Little Mark II's and III's...

There are both types in the BA line, I believe there are several BA models that are class D. Using the term "solid state" doesn't differentiate between any of the classes.

I’m just going what Ampeg says themselves in that link I posted. They clearly separate solid state (page 7) from Class D (page 9) and the BA series are solid state.

Fender and GK do this as well, go look on their websites. The GK RB series heads clearly say "solid state" while the new Legacy heads are listed as Class D. So while A/B and Class D are solid state, every company I have seen differentiates between "solid state" and Class D amps because A/B and class D are different things. Take it up with Ampeg, Fender and GK if you have a problem with it. Here is a good read if you would like to know what those differences are...

You can question me and my comments but, agedhorse? I'd take his word on this.
It's both, a class D amp is class D and solid state.

I might know a thing or two about this subject since I've been designing amps commercially for over 20 years... including class D.

That's called "MARKETING". a Class D amplifier is 100% solid state. This is simply not debatable, it is fact.

Class A/B? Class D?


Only Class S for the upper class.

That's right, in that market class D stands for "diesel"

I wasn't quoting you and Im not questioning your knowledge on this matter. What I AM saying is that Ampeg, Fender, GK and every other manufacturer I have seen clearly separates solid state from Class D. I have posted proof of this several times. As Ampeg says themselves, in the link I posted from them, Class D "is akin to a solid state amp". The word akin means "of similar character". That means the two are similar, but also different. I also posted a very insightful link that explains the differences between traditional "solid state" A-C and Class D. I was correct in saying I thought the Ampeg BA sounded better than the Rumble because it was solid state, while the Rumble is Class D. Thanks.

Ya Agedhorse, you'd better listen and learn from mbell75, he sure knows his stuff...

The Rumble is solid state and happens to be class D, the Ampeg BA-300 is also solid state and happens to be class D too.
