The Guts

 

[metalmarlon]

So any recommendations of settings to give me a running start?

Also I would like settings that will give me some good cleans and good metal between the two channels.

It has the export X101 transformer too. So it is Sumil Class. Any tube recommendations. I want to put EL34s in the outer sockets.

You have to run your VOL 1 much higer for the lead channel.

Set it to 8/9.5 set bass to 1./75, treble to 7 middel on 4 , master as high as you like, lead drive 5/6.5, lead master on 2, presence on 2.

You will find out that the c+ will not let you dial in a perfect lead and clean channels.

I see this amp was the one i bid on a ebay, if you ever want to sell it let me know il pay you more then you bourgt the amp for .

Good eye. I was hoping that it would slip by due to the improper listing. But everyone seemed to be on top on it like me.

I got swept up in the bidding and almost had a heart attack when it closed with me as the winner. Especially because there was no guarantee that it was in fact a C+.

I will make sure to let you know first if I do decide to sell it. But.... honestly... I would not hold your breath. LOL!

Thanks for the settings. I will definitely give it a try.

Its all ok

You proberly end up falling in love with it, but if there ever was one major problem with the C+ is that when you set it for metal lead tones the clean channel is useless.

But again pleas let me know if you ever want to let it go.

Bes regards

BTW was it a real c+ plus ?

Yeah I'm beginning to see that. I don't think I will ever find a head that has both a great lead and clean channel for me and that lets me use my G-major 2 in the loop.

As far as I can tell it is a legitimate C+.

The serial is 128XX which means that it should be a factory C+ and it passed the loop test.

Someone has added a resistor to the outer pair of tube sockets at pin #5. My guess is that it would make the outer pair of tubes run cooler. The bias is pretty hot for 6L6's in the export versions. With regard to running EL-34's in the outer sockets, pins 1 and 8 need to be connected for best results. The problem is that someone has robbed all the #1 pins from the sockets. This is a common practice to use them to repair other broken pins that are needed for 6L6 use.

The cascading gain circuit is going to require you to run the Volume 1 setting at 7-8 at the very least to provide the Lead channel enough signal to sound its best. The EQ toggle switch may very well have a hidden "middle" position that is EQ AUTO, meaning it will only be active in the lead channel. This will allow you to use the graphic to shape your lead channel and keep the cleans thick and full (I really can't stand a wimpy, limp d#*K clean tone).

The extra RCA jack under the chassis has me curious, but I have seen other anomolies from this time period at Boogie.

If you ever get tired of this ol' girl, just let me know. :wink: I'm sorry about that last second bid, BTW. :lol: :mrgreen:

suhweet@! what did it run you?

 

[ryjan]

You got a "Crunchberries"!!! You sob!! :lol:

 

[kiff]

damn that thing looks clean

nice amp. I watched that one til the last second. I seriously cant believe how you guys can pay so much for a 2 channel amp that renders one useless to make the other sound good. Yes i do realize how good they sound but jeez. Still not understanding the hiding of serial numbers. Anyone that saw that auction could plainly see the serial number the seller posted. It was OBVIOUS that it was a IIC+ from the start. You could clearly see the "+" on the chassis in the pics. Congrats on your new amp and your months to pay off a credit card. :lol:

a 2 channel amp that renders one useless to make the other sound good.

I do not endorse that statement. There is a "workaround'" for the clean channel. it's called a guitar volume knob. My many years of playing a Mark I made me learn to be handy with this control. 8)

 

[LPClassic]

Congratullations on a great amp, by the way, pay happy knowing that the amp will keep or go up in value and you can actually enjoy it.

Saw the listing too but was out of my range... of course would have love to have it too. Rock on!

Kind of like how you have a 3 channel amp with one set of controls? BTW, all of my amps (amongst them, 2 IIC+'s) have gone up or kept their value since purchase. How about yours? Don't knock others for their purchases. It's kind of rude. Beauty is in the eye of the beholder.

with all due respect, I cannot see how anyone who has spent quality time with one would perceive the clean channel as being useless...and it is a "sound" investment(get it??)...if you watched it to the last second, you can see that for sure ..now, I wonder what I can get for my C+ Coli...hmmmmmmm 8)

I dont mean to be rude about it, that wasnt my intent. Im jsut floored at what these go for knowing its limitations. As for the mark III I have, it didnt cost nearly as much as that and I coould sell it any day of the week for what I paid, if not more, which was around 900 shipped. After hearing many different clips of the IIC+ and what i hear from my III, Im not seeing a huge difference in tone to warrant the IIC+ costing nearly 2500 more than mine. I guess its all subjective, I personally dont see it but thats ok. If someone has that kind of money to spend, then more power to em. Glad this guy got the amp of his dreams and had the money to pay for it. I guess i just need to play one in person rather than listen to clips.

...don't worry, I could find out quick....all while rolling some pennies. 8)

 

[JOEY B.]

In all honesty, you really need to play a loaded C+ back to back with your Mark III. This is the only way to come to any real conclusion about the value. Soundclips and judging from any past memory are sketchy, at best. Even listening to someone else A/B-ing the amps will not get you the full effect. You will have to be in the drivers' seat to fully understand. 8)

Very good assessment JB !!!

The bias has to appear hotter on the export because the plate voltage is 25-30V less. In the end with tube pulling a load the bias is exactly near the 105 specs,
but adjusted for the lower Export voltage. To fix the outer sockets to run EL-34's you can use pin 6 from the inner sockets. The amps from June-August 1984
all seem to have bad socket clamps and wiggle so bad that the pins snap, mainly on 2 and 7 for some reason. The best fix is to flood the pins with solder to keep
them from flexing. The extra RCA jack for the reverb is a replacement for the original one under the board. The person who repaired it probably did not know about
the grounding issue and ran a new jack. The original jacks input is on the V3A pin 2. The trace goes under the .01 orange drop and you will see the solder tab from
the jacks is connected via a hole drilled through the board. It's impossible to fix without removing the preamp. The 1 wire mod is the Boogie repair, so I don't think this was
done by Mike B. The 10K resistors over the 220K's is a little goofy just to get 210K. I would remove the 10K's because the 220K not only sees the negative bias voltage,
but the preamp signal from the PI. The C+ had four different face plates depending on the chassis length and EQ option. This amp, like all EQ optioned amps has an EQ
auto function. This one is in the middle position.
