Peavey Classic 30 - disassemble to replace speaker?

[humfree]

Just grabbed one of these cheap and was looking to replace the speaker, but it looks like I have to take the entire enclosure apart. This one was made in 2005 and it has a small backplate along the bottom that is fixed (not sure if they are removal on newer models). Can I squeeze a speaker in there by just removing the tubes or should I plan a complete breakdown to get the job done.

Thanks

You have to pull the chasis out.

I remember replacing my speaker and I vaguely remember complaining about the same thing. Maybe someone has a trick to this by now ? :)

I helped my buddy replace the speaker in his Classic 30 and we pulled the chassis out. Thankfully he liked the new Celestion anni G12H30 much better than the blue marvel speaker.

[meterman]

yeah it's a PITA you have to pull the chassis watch your knuckles :)

[recto-robbie]

its not hard at all, just make sure your fingers stay out off the circuit board when you are removing and replacing. It can get heavy and awkward holding it with one hand while using the driver with the other.

Unfortunately there is no easy way. Make sure none of those chassis screw holder things fall out and you forget to reinsert them.

think its 4 top screws and 2 on each side

By the time you get that speaker out, you will have a completely empty cab...I had to remove the tube cage, tubes, chassis, reverb tank...to put on a frickin beam blocker...I hope to god I sell it before I decide to replace the speaker lol

how frickin stupid is it to design an amp the requires complete disassembly to swap the speaker...isnt speaker swapping the second most upgrade/mod to an amp??

[Ramblin390]

I dont people were so ocd with their gear before these forums popped up when the classic was designed-could use an update with a taller cab and a mid scoop, not boost swtch

I don't think anybody that has OCD is going to be able to read your post.

Guess I touched a nerve!

Well, it came with a Weber Ferromax (vintage) which sounds great for cleans, but has sort of a fizz with heavier gain or distortion. I have a big 2x12 cab with a Cannabis Rex and an old EV that handles the gain well, but they are both 8 ohms so I can't use one of those. I don't want to spend a ton of cash on a speaker when I'm not sure the combo is worthy.. I could even see myself cutting it into a head because I am simply not going to experiment with speakers in a box I have to completely break down.

So, if this thing becomes a head, I will have two inputs for extension speakers. I just want to confirm how I will be able to use them.

From what I understand about how this thing runs a load:

The internal speaker is a 16 ohm load.

The extension out for a cab is a 16 ohm load as well, however, if I disconnect the internal speaker, I can run an 8 ohm cab out of the extension speaker jack.

That is what I have heard.. now I thought if you unplugged a speaker from a combo that the resistance would be infinite. Is there an automatic attenuator in there that senses a load before allowing voltage to flow? The manual makes no mention of this and gave me the impression that I could run an 8 or 16 ohm load through the extension input regardless of whether the internal speaker was connected or not.

The mysterious functionality of a tube amp.. jeez.. thanks for the breakdown info - it almost looks like removing the tubes and the reverb tank would do it, but I never like to start a project without knowing how long it will take.. hehehe.. again, thanks!

I have absolutely no data to back any of this up, but I bet a VAST MAJORITY of people don't upgrade a single thing on their amps. Seriously.

It does suck to have to take the amp apart to swap speakers, but I definitely like the small compact design of the amp.

The jack for the extension speaker is a switch that changes the connection from the 16 ohm tap on the OT to the 8 ohm tap.

Don't try to take the reverb tank out, just pull the chassis and you'll have plenty of room.

Any speaker you put in a Classic 30 combo sounds horrible. Disconnect the internal speaker and connect a good speaker and cab into the external speaker jack and now you're talking.

I think a greenback sounds good on the combo.

The ceramic Weber Blue Dog sounds great in mine.

+1 on this method. Shrink wrap the original connections and use a right angle jack and some lamp cord for a new speaker cable.

Also while you have the chassis out, add some self stick weatherstripping on the top & sides of the chassis to make a seal where it comes in contact with the cabinet. Cuts all rattles and keeps the tubes from vibrating.

I think PV puts a small rubber seal there, remove it and replace with the weatherstripping (avail at any home depot).

I put a Emi Lil Texas in mine, its so light now.

Both C.Rex and Private Jack sound excellent in them.

[smolder]

nearly anything will sound better than the blue marvel, well worth the effort, but that cab will not optimize any speaker that I know of or tried in mine.

I put a Celestion V30 in mine and really like it. Pulling the chassis is not hard. Six screws. Keep track of which are which, though, as I believe there are two different lengths involved.

[thewex]

anyone know if its the same method for the c50?
