I saw a Mk III opened up and it was just incredible the work they put into those amps. It is a project beyond most on this forum. it might look difficult, but tube amps are far from rocket science to be honest, the technical part is pretty straightforward as long as you keep looking it in a systematical way. The more difficult thing is the 'tone' part, since tone is very subjective and can't be put into formulas like rocket science can. Link to comment Share on other sites More sharing options...

Yeah, Boogie gear IS very expensive. $7495 for a ROAD KING!!! Even the Rect-O-Verbs go for a whopping $3500!!!!!!! Now (thanks to the help), I have worked out how to read how the circuit segments fit together. I'm going to omit the reverb section, as I just want reverb on the other amp which is already built in (I am really keen on the Switchblade by H&K). I would like to get a Studio preamp and mod it, but somehow its diagram (well last time I looked) seem a little more difficult than the proper IIC+ preamp diagram. In some ways it seems better to make the whole thing from scratch. Plus, I want to make it so the lead circuit is engaged all the time, as I will use a volume pedal to lower the gain for dirty-cleans in real-time, and use the other amp for proper clean sounds. I'll have another read- woh alot's been posted here since last time I was here. thanks for the responses. Link to comment Share on other sites More sharing options...
Members petejt Posted June 25, 2006 Author Members Share Posted June 25, 2006 Originally posted by RoboPimp I think there's plenty of people here who could throw one of these preamps together. there's some really good builders on this forum man! but you do make a point that it's NOT something to be attempted by someone for their FIRST project? Not a good way to try and save a buck... buy a MKIIB or C or III or IV !!! It's gunna be close enough mang! A used QUAD preamp might be the way to go if you want a MK sounding preamp. well, technically it's not my first amp-building project. I have built a solid-state amp, for a doorbell.....

Members petejt Posted July 19, 2006 Author Members Share Posted July 19, 2006 hi folks, I'm still crazy on building my own amp. I've learnt alot more now and can read the diagram, problem is that it is a bit blurry and hard to read some of the component values. What transformer will I need so it will work with 240Volts AC? Oh, also I don't want to build the reverb circuit, as I will be using another amp alongside that has its own reverb. I want to build the preamp with one input and two outputs (stereo). anyone who has built this preamp, the actual IIC+, have a proper correct clearly drawn diagram? if so, please post it, thanks.

Members knucklefux Posted March 22, 2008 Members Share Posted March 22, 2008 i can actually point you to a 99% accurate MKIIC+ schematic... and you might as well hang up the idea of using that particular graphic EQ...those inductors are not readily available. well, not in the states anyway.

Members petejt Posted March 24, 2008 Author Members Share Posted March 24, 2008 pics or it didnt happen mang. It didn't happen. I got a MarkIV instead, and it has well impressed me, so much that I have no desire for a MarkIIC+ preamp now, as I have one already plus a whole lot more Link to comment Share on other sites More sharing options...

Members Angry Grimace Posted March 24, 2008 Members Share Posted March 24, 2008 And the OT is what gave the Mark 2C+ it's "unique" cough cough, sound... Eh, the Mark IIC+ sounds virtually identical to the Mark III in my ears Maybe I'm the only one who thought paying $3K for the IIC+ is probably the biggest waste of one's musical dollar.

Members micro66 Posted March 24, 2008 Members Share Posted March 24, 2008 I've built the preamp and it doesn't sound like MK IIC+ without MK IIC+'s power amp. Which you can't build because you don't have the output transformer. I have filled in questionable parts in the schematic with values from MK IV and MK III schematic, and tweaked it afterwards as well. Link to comment Share on other sites More sharing options...
Members OverDriven Posted March 24, 2008 Members Share Posted March 24, 2008 It didn't happen. I got a MarkIV instead, and it has well impressed me, so much that I have no desire for a MarkIIC+ preamp now, as I have one already plus a whole lot more As much as I love my Mark IV, I have to disagree with you that a IV is the same as a IIC+, but with more features. IMO the only thing on earth that makes a better sound than the MKIV lead channel is the Mark IIC+ lead. It's like the MKIV lead channel, but the difference is is the low notes. Up high, you would have a hard time telling the difference. When you go down to the lower notes on a Mark IIC+, it opens into this insanely aggressive growl that sounds SO DAMN GOOD. On the downside, the IIc+ is far more expensive and far less versatile, so I'll take the Mark IV any day. Link to comment Share on other sites More sharing options...

What I meant was, is that the preamp of the MarkIV is the same as the MarkIIC+. But, as you mentioned, the MarkIV has the extra features. So I was wrong in not being too clear about it. Yep, that insanely aggressive growl is exactly why the MarkIIC+ is so coveted, me included. But I reckon I can make my MarkIV very similar to that, in fact I reckon I may already have. It helps though to use another amp alongside it though. I was just checking out your clips on netmusicians- they sound excellent! Link to comment Share on other sites More sharing options...
