Ask Ampeg would be a start I reckon.

Super 12 will do that fine. Watts is down to how loud you want to go. It can take them, but it doesn't need them.

[quote name='BassTractor' timestamp='1362679135' post='2003305'] 2) the DI button is not switching between ground and lift (whatever those might be if they even exist) but is a ground lift switch [/quote] Think its switching between grounded, and having the ground connection lifted (so not on the ground any more).

SM<PS is switch mode power supply, pretty unrelated to the output. You can make a valve amp with SMPS, think Peavey did one.

[quote name='discreet' timestamp='1362665997' post='2003025'] I'd say that was around 99% of those on this forum. [/quote] Well, yeah, I had that in mind, and figured I should include the exception.

If it is an Orange terror, no probs with having no load. The impedance selector is a fudge. Should be noted it isn't the class that causes things to be upset by no load, its the use of an output transformers, you could make a class D amp with an OT, and one with valves, and it would be upset by no load, ditto with solid state amps with output transformers.

[quote name='Roland Rock' timestamp='1362648949' post='2002571'] I read that as a mini rant about people who are only into 'crappy pop music' and the cult of celebrity, rather than quality music, and the subsequent difficulties of getting 'real' music into the industry. Of course I've been known to be wrong :-) [/quote] Not that specific, especially since the industry has long since become irrelevant to music. They'll turn up in various guises. The ones I have to deal with most are the buy all the gear some dead guy they listen to exclusively used, barely ever play, never listen to themselves (because that wouldn't be listening to the dead guy). Kind of a cult of personality, except instead of a personality, they have vintage gear. But their money spends as well as anyone elses. Interestingly, you get similar, but are actually keen on the music, but still gear obsessed, and they tend to be penniless. The other easily spotted classics are the ironic band t-shirt wearers, who have no clue about the associated music.

Realising the amount of people who don't like music but pretend they do anyway, and ruin everything for everyone who does.

The string motion produces the sound and the motion is a product of a bunch of factors, the simplification is in flexibility, the round windings damp the strings less than flat windings that are closer together. Really, for the purpose a pickup acts like a microphone, just instead of reacting to air disturbance from the string motion, it is reaction to magnetic field disturbance. Maybe picture a string of round beads vs a string of flat discs, if they are all packed tight, the round beads will tend to bend easier than the discs, that damps the higher frequencies.

Really grotty Selmer 50w guts here: https://ampstack.wordpress.com/2013/02/03/selmer-treble-and-bass-50-sv/

Would guess marshall branded Celestions would be likely.

[quote name='iceonaboy' timestamp='1362592735' post='2001865'] That's why Ampeg push their 8x 10 , because it moves far more air than 2 x 18's would . I [/quote] Do you mean 'how' they push their 8x10. As in, with totally false statements.

[quote name='Baxter' timestamp='1362574127' post='2001467'] I got it from an old guy who fixed amps and no one had claimed it for over a year. He gave me it for the cost of the new parts! [/quote] This guy got any other toys going?

Depends if you like a massive notch where the output from the speaker and from the scoop are out of phase. Gives that loud and 'bassy' but messy sounding thing There was a write up here: http://www.speakerplans.com/index.php?id=faq12 but the throw thing is a bit dodge, probably the room effects cutting out the bit where it does work, and the in build scoop taking out the bit where you can hear it closer.

Thing is, if matching four numbers on a chart with some dials is scary, messing with glass things connected to a few hundred volts should be terrifying. Plus there'll be a whole bunch of good valves binned when the microprocessor misidentifies one and the user isn't sharp enough to spot the anomalous readings, or just because there is dirt in the socket. Actually, its pretty standard for Orange amps to use only one half of one of the pre valves, so you can cheerfully use one that has failed on one side.

Scoop bins with the speaker showing totally suck.

A DI that has the sound you want would be ideal, Sansamp if that is your sort of thing. Ground lift is to deal with ground loop issues, only to be used if there is such an issue.

Sealed should be stuffed.

Don't think the B500dr is a valve one. Something is wrong though. Could be the cab. What noise is it making that says you can't turn it up more?

Where does the affiliates fit it? Also, what about people who have made donations in the last year?

Problem might be mostly in the reviewers not actually knowing anything about what they are talking about. Probably trying to appeal to the equally clueless. When you consider buying something marketed to the ignorant...

How much heat are we talking? Use a soldering iron on frets to get them out, and the wood is happy enough.
