I have been skimming the threads here for the last few weeks trying to research and learn what I could do to my board to make it sound stellar. I bought this board a year or so ago for cheap...$87.00 in immaculate shape on the Bay. The sound I am wanting to get out of it is what most people I assume want...warmth, punch, detail and clarity, and overall total control of shape and depth, by way of input gain and EQ.
I use all outboard mic pre's for tracking; Neve's, API's, JLM Baby Animals and Green pre's. So my tracks are pretty much already "colored" and warm. I used to have a pair of the RME Multifaces and then went to the Lynx Aurora 16 which is light years ahead. I didn't know I had a murky, foggy mix until I hooked up the Lynx. So with the Lynx I output 16 channels to the board and am getting more or less the "colored" tracks on a "colored" board (am I sounding racist? hope not :green: ). The Yammy is transformer coupled throughout with the Tamura iron.
I guess what I am saying is I need this board to sound less fluffy and more transparent/in your face. The overall soundstage is somewhat scooped, if you will. Unlike that of a Pultec when you kick the bypass off and the tube just makes the track leap off of the monitors. I'm thinking another board (transformerless) might do the trick but I don't have the money to buy one of a caliber worth using. So what mods could I do to the Yammy?
For instance:
(BTW)I already recapped the PSU, master fader and channel strips audio path lytics with Panasonic FCs.
I swapped the JRC 4558's in the EQ section with OPA2604's and bypassed the vregs that dropped from +-24v to +-16v. So now the 2604's are getting the full +-24v.
Next considerations?
Maybe a different output transformer for the master channel? Cinemag, Edcor, Carnhill, etc?
Change the master strips to a different type out? Class A, AB, change opamps to 99v, 990, 2520, etc? I just don't know.
Here is the schematic for the channel strip. Page 14
