Hello,
for the past 2 years I have been researching this build. and yes I have searched these forums. It appears that the bulk of the LA-2A DIY on the net is from 2006 to 2009. I can not find anything recent!? I would like to know from confirmed recent diy la2a builds about input and output transformers as I am very concerned about what to purchase and need some help.
I hear sooo much talk about, making a transformer to kind of work. .
I want to buy transformers that perform like the originals, look like the originals(fit in the chassis) and don't need to be circuit modified. Can anyone help me out from your own personal experiences.
What I have found are these confusing problems.
1.adding a capacitor to drop the impedance to kinda make it work.
2.reverse wiring from 1:4 and 4:1
3 then the problem of the line input being to high and going into mic input
4. The transformers are to clean and no distortion or vintage grind when pushed
5. Sowter output tranny are not a circular shape and wont fit a traditional circular style chassis
The list goes on and on.
Between edcor, Jensen, Cinemag, Sowter and the esoteric UTC and a million other ones ..is there not one that is wire for wire - similar size and shape. Impedance and ratio for the diy guy that is bolt in , no mods and works???
My concerns with purchasing the wrong transformers are : being to clean, to much gain, not being line level, not fitting conveniently in my chassis, having to alter the tranny with ambiguous capacitor values to get something to kinda work... gains being all wrong, etc etc. Has anyone installed and purchased I/o trannys and had success with the clone being similar in function and, gain and levels to what I have used as originals in the studio?
I have built the compressor using a circuit board with circular holes for the I/o xfr
