30W is conservative by most standards today. The amp used needs to match the playing style and the band's volume.

I think that there is couple of things that you could try. FIrst get the amp checked out to ensure that the power output is optimized. Then, I would try it with a 215 configuration and see if that allows you to keep up. If it doesn't, changing the speaker probably isn't your solution.

There's always mic'ing the cab.

It is for some but not for me

The gig I want to use it for is a low volume Blues band, vocals only through a cheap PA. If I went the 215 route, I might as well just use the head and my old JBL 215 cab. Lugging two 115 cabs as opposed to a 215 is actually more of a pain than you would think, without roadies ! I was hoping a more efficient driver would get me over the hump. I guess there is only one way to find out !

Hi,

Just received my brand new Ampeg B15 Heritage (2012 / 52 of 100), but the top is stuck to the cabinet!! I released all those 4 latches but the top doesn´t get loose!!! I guess the glue was still wet after attaching the tolex and they put the top in the storage position. And now the glue has dried and I can´t get the top loose to turn it around. Anyone ever got this experience? I wouldn´t like to use a screw driver to destroy the tolex and wood - nor a rubber hammer to destroy the tubes...Heck - I´m in the bad mood - I waited so many months to get this baby home - I think 9 months.

BR: Yeppe

Nothing wrong with the amp. Your drummer is too antsy. He shouldn't be banging so hard in a low volume blues band. Maybe some worm powder will settle him down.

Congratulations on the new amp Yeppe.

Maybe the wood has just expanded a bit. Push downward, one hand on each long side first. This might dislodge it. Then carefully try pulling upward from one corner.

First set is usually no problem; then the alcohol sets in.

Does there appear to at least be a tiny gap between the front and back edges of the lid and the cabinet? As David mentioned, I'm wondering if the lid is fitting too tight in the opening? There shouldn't be a problem with any tolex glue as it dries relatively quickly, plus the cabinets are shipped elsewhere to have the amp attached and go through final packaging. If the problem isn't the lid fitting too tight I'm wondering if it could be sticking to the gasket for some reason. Perhaps you could try slipping a credit card in between the lid and the cabinet (from the side) if that is the problem.

Please let us know what you find out.

Never mind.

JimmyM · #**790** 01-09-2013, 05:00 PM

BTW, I'm dying to hear what happens with wessman! He asked me in a PM, and I didn't even think about the possibility of weather causing expansion/contraction. Again, I am a poor shell of a club president.

Those were the good old days. The Diamond Blue tolex was so plentiful and cheap ($7.90/yd) you could put it on anything, even the overhead cabinets in your home office.

I would think it would have to be the weatherstripping creating a seal or the lid swelling a bit and sticking. Pick the whole thing up, turn it upside down and shake it violently, that'll get results

...or you could just use Mark's credit card idea.

You could always stir an Ativan into his beer at setbreak.

kuratacus, does yours have a Jensen C15n or the EM1500? I'm curious to know when they switched to the EM1500 - it was sometime in '63.

Mine has a C15n in it. serial states it's was made in may as well.

Some people get loud when they drink.

Nice Mark. My wife got into my stash and made a purse out of some of it.

I hope that he's enjoying his HB-15!

First time I built a lid it was too big to fit the cabinet opening after I installed the vinyl. I learnt my lesson on expansion the hard way. Shrinkage in the cold, well I won't get into that.

Interesting, looks like you've got one of the very last B15n's made prior to the change to SS rec. I've found that you can get a really nice pick tone with the C15n's - a really nice percussive thunk! I'd like to A/B the C15n and the EM1500 just for kicks one day - a P15n too. My C15n is a recone so I'm not so sure how similar it sounds to an original cone. I've also got another Jensen Concert that looks similar to the EM1500, but it has a red label as opposed to the blue, I'm not sure of the difference - I don't know a whole lot about those old Jensens.

The EV TL-606 ...

I should note, my friend (John Straw - great bassist) with the Thiele cab/ 3015 is driving it with plenty of power. Saw him using it with 200-300 watt Carvin class D head and it filled up a bowling alley with no PA support.

I'm kinda thinking the same but with a PF35O, maybe even mounted to the lid. That'd be a sweet little light rig you could go to war with.
