Cleanest boost for 1950a

[Andrion]

long time away from here! happy to be back;

I need a simple volume boost that fits in a 1590a to place in my amp's loop switch, so I need the cleanest boost possible;

I know there is Amentun boost, AFT preamp and Enchanted boost that all fits in 1590a, but which is the cleanest sounding?

there is also the "not okay" boost from CGI; anyone have an experience with that?

thanks in advance!!

if you're intending to run this in your FX loop, you'll want a boost with the largest headroom possible. - i.e. preferably something running at 18V or more.
for best results - this factor will matter more than whatever is 'cleanest'.

You can tweak the values if needed.
Prob want to run it at 18v in the loop(jinks)
Could probably fit this in a LB if you wanted.

It’s just a bit too long for an LB. Should for fine in an A.

to make it run at 18v I only need to use caps with at least 50v, right?

35v is fine, it's about double the rating. You get diminishing returns using higher voltage caps, especially considering the footprint of higher voltage electrolytics. Most film caps these days are 63v and higher, you have nothing to worry about there.
