Im curious.. are you a guitarist or a bass player? :lol: Just kidding.. Those settings must be shaking the walls! :shock: For me the Pull Deep is only useful at bedroom levels and not at full gigging volume, as the bass frequencies can become heavily exaggerated when volume is increased...

Are you planning to build your own C+?? :lol: It seems you misunderstand what is required here and Im worried your going to end up modding your Quad incorrectly. The Quad doesn't need any major alterations and/or circuit boards added, we are talking about a few minor Cap and Resistor changes...

Pm'ed Anyone else interested in this?? Looks like I might be making an instructional video!! 8) Shane

The Quad is a tonal beast.. Sold my Triaxis with no regrets!! :mrgreen: Shane

Hey Friedmett, Just in case its not a tube problem, I would inspect the capacitors for leaks when you have the lid off. Good Luck! Shane

Howdy, If anyone wants to understand the differences between the Mark series amps/preamps I highly recommend you learn how to read schematics, then all will become clear. Its funny that after 25 years these questions about "which amp is closer to this amp" still come up.. but it will forever...

Ive C+ modded my Quad preamp and MKIV and both were tonal improvements in my opinion, the GEQ reacts a little differently. Overall the tone becomes more percussive and bitey.. killer rhythm tone for rock or metal. You don't need to worry about having simul-class, I run my Quad into a VHT-2502...

Howdy, I highly recommend using the FX send rather than the main outputs.. the difference will shock you! and with the main outputs the louder you turn it up the harsher it becomes. Littleb, are you referring to the pull deep knobs? eg. Channel 1 Pull Deep only works on Output A and Channel...

The C+ mod only affects the lead channel on the Studio, (affects both on the Quad's LD2) there will appear to be slightly more mid gain because of the boost of the upper mid-range and high frequencies, this will help when setting the Studio for two useable tones using the shared controls. I...

There's a few errors in that Studio Lead circuit diagram from what Ive researched. The 680k should already be a stock part before the 1M pot and the stock 214k is actually a 274k, which is the already the correct value. So both of these do not need to be done. Also the 500pf off the top of pin...

Yep... :D And it only takes about 5mins to do it! :twisted: Although the stock Studio tone is smoother than a C+ so its really just preference. Im planning a custom C+/Studio hybrid tone for my Quad's Lead 1 channel. Shane

Howdy Masher, Yes the 1M you found IS the one in the diagram, if your Studio works and sounds fine then all should be well. Although you might wanna inspect the electrolytic capacitors for leakage while you have it open. It's good that your willing to have a look inside and fix it yourself...

Masher, Follow the wires from the input to where it meets the pcb and you should find the 1M resistor mounted on the board, off pin 2 on that preamp tube. Resistor color code = brown black black yellow brown = 1M. If someone added another resistor to the input like in that pic, then they did...

Hey Caligulus, yea the idea is to make the studio have switchable options so its more like a standard Mark Head. Hey mboogman, Didn't you have the 270k in there as stock? Bigger resistor = less gain and this will affect the tone slighty as well. Also you might want to try 1000pf instead of...

Hey your welcome Wezzley. That article came with my Quad when I bought it 2nd hand, quite a nice bonus I thought. I certainly have ZERO plans to sell my Quad. Is it ok if I PM you Wezzley? Im curious of your opinion regarding the Quad vs Mark V and I don't want to hijack this thread. Cheers...
