No, although a lot of them have back cover/grill/things on the back of them that might be there to stop you from "killing yourself". So those may have to come off first.
#4
Well, most do but you have to be pretty lazy for that to put you off buying one.

which ones don't need to be opened up to remove tubes?


That's a pretty broad question. There are thousands of tube amps out there.

Why don't you name a few specific amps you're looking at?

And like the guy above me said, you've got to be pretty lazy (or cheap) to not pick up a screwdriver and give it a few turns. Don't let 30 seconds of work put you off.

Please tell me your not buying an amp solely on the fact you don't have to unscrew four tiny screws to change the tubes every couple of years, there are far more important factors like, I dunno, what it sounds like.....

My VK has a, like, grill-cage thingy around it that i have to unscrew and take off. No big deal, though.

Well I can tell you that if that would have any input on your amp, you're about the biggest idiot ever. It takes about 30 seconds to unscrew the screws and it's real easy. Not only that, but you have to change tubes about every 2 years. Because your question is just so stupid, I'm not going to answer it. Why does it matter anyway? It's not hard to unscrew or anything!

well i read a lot of reviews that are like- this amp is really hard to retube like the crate palominos, the traynor ycv20, peavey windsor studio
#12
Well really it isn't. Those peoples are rather dumb then. My Rocker 30 is among one of the "harder" amps to retube. You need to unscrew the actual amp part from the combo. And by hard tha tmeans it takes 5 minutes. I've retubed a head and biased it, which is a bit harder, but all of the amps you are looking at doesn't require bias so really they are super easy to retube them. You'd have to be a complete idiot not to find it easy.

I think hes asking if are there amps that you can bias without taking out the chassis.

Yes, a lot of newer amps, I know the JCM2000 line, allows you to bias the amp without ever opening the chassis. There are leads accessible from the back of the chassis that allow you to measure the bias current, and a trimpot that allows you to adjust. You just pull the tubes, replace, and re-bias on the spot. Very easy to do.

But other amps require you to go into the chassis to bias a set of power tubes. Well, some amps, if your amp is cathode bias, you don't need to worry about biasing. My amp needs to have the chassis unmounted and I have to bias from inside the amp. Its a real pain to do.
#14
Actually none of those amps requires biasing though! All you do is unscrew the amp (if needed, which means, unscrew the cover, takes about 30 seconds). Remove the tubes that are to be replaced. Put in the new ones. Screw the amp back. Done. Takes a maxium of 10-15 minutes.

I don't even keep the back cover on the back of my head. I like to let it ventilate a bit as it gets beyond hot back there.

Same thing with my H&K, but I'm so lazy I use a drill with a phillips bit on the end. I have to take out about 8-10 screws and remove the chassis. And all that effort is worth it.
I wondered why the frisbee was getting bigger, then it hit me.
#17
^Yeah. It's not like its hard. How can unscrewing 8 screws be hard?

Yeah sure, biasing is a bit harder if your alone (depending on if your amp can stand on the side) but all the amps mentioned are cathode biased and requires no biasing, so all you do is in the worst case scenario to unscrew the screws, which is SUPER EASY!

You would be surprised. Well, you were actually from the looks of your first post! LOL People are scared of tube amps, if they aren't familiar with them it's the "unknown". I take apart my gear after I get it home just to check it out. See which way the gerbil runs on the wheel in there.

My old Traynor YCV50 was autobiasing, so maybe check further into that Traynor.

Besides that, how do you get the tubes out? Don' flame, I'm new to tube amps.

Get an old cloth or tshirt and firmly but gently pull and wiggle it out of its socket.

Same with replacing, use a small cloth and firmly work it into the socket. Try not to touch the glass with your hands as the oils in your hand is not good for the tube.
#23
^I've heard some people say that's BS, but can confirm neither.

Otherwise, yeah all you do is jank it softly and pul it out.

It is BS. I've got a box of about 30 preamp and 20 different kinds of powertubes that I've been using to experiment with different amps over the last 2 years. None of them have any problems from getting touched. Tube vendors would also warn everyone if there was actually a problem with it. The tubes get nowhere near the temperature of something like a halogen bulb, where the oil from your hands traps the heat against the glass and weakens it at that point. I used to worry about it, until I saw a guys old Fender silverface Bassman that still had the original tubes in it. They looked like someone smeared grease on them there was so many fingerprints. Was working fine like that for decades.

There is merit to using a cloth though, so on the odd chance a tube actually broke, it wouldn't go directly into your hands. I've had this happen removing really old tubes, but never putting in new ones.
