Topic: Vintage Modern 2266C

So long story made short short I picked up a Vintage Modern 2266 combo on a trade.  It has Ruby Lion KT66's in the power section and stock Marshall 12AX7's in the preamp. Can anyone make suggestions on tubes and any settings they like.

Re: Vintage Modern 2266C

The white channel seems to have much less power. Could it be the preamp tubes need replacing or is it always like that?

Re: Vintage Modern 2266C

The "white" channel is engaging the full pre-amp section of the amplifier. It should be louder than the "blue". You may have some bad power tubes.

Re: Vintage Modern 2266C

I flip flopped what I meant about the  white and blue channels

Re: Vintage Modern 2266C

Your amp is normal then. It is not a 2 channel amp. The LDR should be thought of as a "portion" of what the HDR is. THere is a very active forum for this amp which you might find helpful. The person who designed the amplifier (Steve Dawson) posts on it frequently.

Re: Vintage Modern 2266C

I have the head and I find that the eq section doesn't seem to do all that much, other than the presence knob.  The real magic in tonal variation is with the Body and Detail knobs.  At least that is what I seem to encounter.  If you just sit and play around you'll get quite a few tones out of it.  They're cool amps and match well with other amps too.

Re: Vintage Modern 2266C

If you think of  the VM like a jumped plexi, it makes it easier to dial in tones. I treat Detail and Body like Vol I and Vol II.

Re: Vintage Modern 2266C

Thanks for the link. I just registered.
I've heard its like a hot rodded JTM45 so I'm very eager to keep playing with it.
Thanks for the help guys.

Re: Vintage Modern 2266C

The guy SteveD from that site is telling people you can run a class5 combo into a 4 ohm cab on that site.  I would never run a 16 ohm ext speaker jack into a 4 ohm cab.

Re: Vintage Modern 2266C

SteveD designs amplifiers for Marshall. He designed the Vintage Modern and Hendrix JTM45/100, I believe the YM model, and was working on a Gary Moore amplifier. He knows what he is talking about.

He very well may know the ins and outs of building amps. I see you have some nice gear so I'm sure you know your equipment pretty well. Would you ever recommend running an amps 16 ohm output into a 4 ohm cabinet?  Not trying to start an argument but that's some advice that turned me off to that forum. Everyone here is nice and friendly  and gives good advice. I think the Marshall amp forum can get quite childish ay times but there are some good people on there that give good advice like people on here. Don't think I'll be visiting that forum much.

Blimey! Must be some mis-communication going on there then!

Re: Vintage Modern 2266C

I once ran a JCM 800 (50 watt head) no cab, just the direct out for about 10 minute.  Couldn't figure out why the fuse kept blowing.  Turns out the transformer blew and the fuse was blowing to keep from something seriouly bad from happening to me or the amp.  Local shop replaced it for $50 and I learned a lesson about making sure you know what your getting into before you buy it.

Re: Vintage Modern 2266C

Steve Dawson designed the Class 5 amp...he's not a hack and he's certainly not a villain. Here are his quotes regarding the Class 5:

"Nothing has changed from the old circuit to the new one except the 'bedroom trick' is now integrated on the output. The old version or the new version is not bothered by impedance mismatch of 4, 8 or 16 ohms. It is optimally designed to deliver 5W into 16 ohms but will give less into 8 and 4 ohms."

"The output transformer is designed to give maximum power transfer of 5W into a 16 ohm load on the combo. If the load is reduced to 8 or even 4 ohms then maximum power transfer will not be attained. However the difference in perceived volume may be quite minimal in relative terms."

Would I connect my Super Lead at 16 Ohms to a 4 Ohm cabinet? No. Would I worry about connecting a Class 5 head to a 4 Ohm cabinet based on the designer/builder's advice that the transformer is designed to handle that? No.

+1, Steve is a stand up guy. Certainly wouldn't intentionally steer people wrong on a "Marshall" forum.

I can say from personal experience that some impedance mismatches are ok. My Mesa Boogie Rectoverb has 1 8ohm out and 2 4ohm outs for parallel 8 ohm cabs. In the manual for the amp there is a couple of pages complete with diagrams depicting safe and unsafe impedance matches as well as a description of how it will change your tone.

It probably depends on how the amp is made and if the transformer can handle it.
