Ampeg B200R

[Sparky Mark]

It wasn't fixed that long ago and I bet that a proportion of the units now hitting the market are reworked from that stock. Other than some rattling I wasn't aware of any other common faults. I gave up waiting and cancelled my order and now don't have space for one but I still love the look.

That was a old problem that was fixed a long time ago.

I shut mine off if I switch the plug from horn to no horn anyway.

So just so I don't blow up mine when it arrives -- it is okay to unplug the tweeter, just so long as the amp is not turned on?

Listen, the first thing I would do if I got one is unplug the tweeter while it's on and see what happens

The second would be to phone whoever you bought it from for a Return Authorisation Number!

Jerrold Tiers posted in June 2008: "Not a mis-communication............

The overseas vendor decided to re-design the PC board, without any notice to us, and they missed the fact that one of the pins on a jack was NOT connected to anything.... for a reason...... they grounded the pin, and the problem resulted.

We had to get some temp labor in and go through the entire shipment, as well as 'adjust" the vendor a bit......."

I think this problem was first reported in early 2007. One downside to this amp is that you can't connect an extension speaker.

I've got a few friends who are amp builders so if I have issues I'll run it by them. Keeping my fingers crossed in the meantime that I'll get a good one.

I did do a little exploratory surgery on my B200R after the rattle got so bad that I replaced it with an Acoustic B200 many months ago.
Turns out that the amp chassis is screwed to the cabinet through very lightly engineered bits of bent metal, and in my case, two of these attachment points actually broke off in the process of simply getting the chassis separated from the cabinet. Easy to see how a rattle could develop given the flimsy construction.
This is especially concerning given that the chassis needs to be removed to change the amp's fuse, or switch out the preamp tube!

Thanks for the tip. I'm anxious to try mine out, hoping it's a good one!

...I figured at that price at worst I could pull the amp out, plug the hole and still have a cool looking Ampeg 15" cab...

Just so you don't have your heart broken, the drivers used in the combos and the drivers used in the SVT115 cabs are different.
