Great video. I actually liked the stock tubes better than the replacements. I guessed the JBL as speaker B so looks like I was right on that. I'm currently messing around with speakers for this amp. I really do like the stock speaker, but I also have a Weber 15A150 (love the honk/woodiness of the alnico) and a JBL K130 (haven't tried this one yet).
Thank you! Yes, I wonder if just the preamp tubes were better stock or just the power tubes. Or both? I should try that too. I do like the stock speaker too actually. Especially when cranked. Someday I might try to convert this amp into a tweed deluxe, which it almost is.
@@fuzzyloomchannel There is something about the grittiness of that amp when it is stock. It misbehaves in the right way. It really doesn't have much clean tone, and I've started to accept that. I'm just going to appreciate how well it does the one trick.
@@aaandersonmn Yes. Maybe we should stop "fixing" things. It's like that person that aaaalways has to add and remove something when we're ordering pizza. Just have a frickin capricciosa, will ya?
Great comparison video! I will say though, I think the 12AT7 is not the best fit for the amp; it makes it way too clean and, by then, with more powerful speakers, makes the tone a bit lifeless. A good 12AX7/7025 or, at most, 5751 on the v1 would be best, in my opinion, of course. I noticed a difference between speakers but I can’t say I liked any of them better than the other, because I was hearing less signal (from the 12AT7). But I am also on the lookout for cool old 15” to assemble a cab and maybe even another one to try on my Excelsior. I am thinking of selling it but… I always think I’ll want to try to modify the circuit a little bit in the future, as a project. At the moment, I still don’t know how to read schematics or even work on amps, but it seems a cool and deserving amp for a bit more shaping.
Thank you for watching! I definitely could have done the whole thing differently, but unfortunately now I've sold it because I needed cash. I obviously regret it. Don't sell yours. I also realized I kind of liked it stock tbh. I should have tried different tubes with other speakers though. I also recommend trying it through an external cabinet. It sounded awesome through a JBL D120-F in a Supersonic cab.
Hm, I have only tried them as guitar speakers, but they should both be very good for Hi-Fi. The EVM is definitely louder, but I don't know if it is because the cone has been used less or something. I think probably the EVM. Probably.
The Excelsior is a 50's Tweed amp, set up all wrong. You are compensating by using the 12at7 tube. The first stage plate resistors need changed to 100K and the coupling capacitor needs changed to a better cap and value......then the volume pot needs to be changed to a 1 meg audio taper pot......at which time you can remove the tone switch and replace it with a tone pot.......and the last thing is to change out the .01uf coupling caps off the phase inverter going to the power tubes......change them to .02uf. The range of the value there will influence the bass response.....so any value between .02uf and .05uf would be about right for guitar. The 50's amps used a .1uf cap which can have too much bass response. Essentially this is a single channel Tweed Deluxe. Personally I would delete the trem/vibrato circuit and create the 2nd channel with that tube....so its more true to a Deluxe. There is not much to be done......AND in the power amp, the cathode bias and cathode bypass cap...the cathode bypass cap needs to be 22uf as going higher in value will clean up the amp response. I haven't examined the Excelsior schematic in awhile but this is what I recall from memory.......its really not too far off from being a single channel Tweed Deluxe......they just set it up all wrong with the 500K volume pot and huge plate resistors creating too much gain in the swing of the pot value where they had to cut it back......and the switched tone circuit was kind of stupid VS. using an adjustable pot for the tone control
Mike C amps . . Where are you getting that information? Is there a video, or a write up that you can point to? . . I bought one of these amps a few years ago because of its vintage looks. But I just can't connect with its harsh sound. I've concluded that it has nothing to do with the speaker or tubes. It's just simply the circuitry.

speaker "B" is the JBK K130.
Stock speaker and stock tubes win!
The stock tubes were probably the best, more lo-fi etc. But I regret not testing them with the other speakers.
Gotta admit, I like the stock speaker and stock tubes the best.
They were probably more lo-fi.

Where you at? It looks frigging cold. Lol thanks for the video!
I am definitely in Sweden, Europe. There's white materia outside my window now. I think it's some kind of frozen water.
Great comparison video!

@@fuzzyloomchanneldo you still have your 15-L and trying to sell it please ? I would have sware B was the EVM.
@@leonardo.rafael Unfortunately not anymore.
@@fuzzyloomchannel thank you for your response. Best regards 🙏🏻
Stock sounded better with stock tubes!
1. JBL
2. EV 15L
B is more Fenderish. But I cannot see the answer which is which?
Speaker B is the JBL K130.
B won in my ears@@fuzzyloomchannel
@@mariuszfoks5976 Definitely in mine too! Wish I still had it.
EVM15L is speaker A, though it reminded me more of an Altec 417
K130 is speaker B
Don't wanna reveal it, but it's been a while. You were totally right.
which one is better for home hifi
Hm, I have only tried them as guitar speakers, but they should both be very good for Hi-Fi. The EVM is definitely louder, but I don't know if it is because the cone has been used less or something. I think probably the EVM. Probably.
speaker A had a fuller sound
It probably did. More mids and all!
@@fuzzyloomchannel try a celestion alnico sometime. i have a 10" gold i use with different amps.

I need to try all that! I'll see what I have laying around.

@@234dilligaf Same here. It would be good with some mods to have something close to a tweed deluxe because I dont like how this amp sounds stock.
