I would put in Mills resistors while I am there, 2-.22 uf caps on the input
And 4 caps on the output new ones maybe all 1 uf all are 400v
Some models had 2 caps at .47 value you have to check.
Parts connecxion suggested the Obbligatto Gold.truthfully I think these better the Auracaps and are similar in cost for under $100 you can transform the 2000pre. I put in a Hifi tuning Supreme 5 a in place of the crap steel fuse, and just used the Chinese tubes gor a 100 hours to runin.
Best rectifier Bendix6106-5y3 or Brymer, the inputs 12at7 many choices.I am using Sylvania black plate triple mica Gold series industrial grade12at7s.
Look for 50s black plates all are pretty decent ask for low noise matching
For this is a SET preamp stage and picks up noise anywhere down stream
But when tubes are great detail and dynamics excellent little tube rush.
Herbies footers and Titanium tube dampers make A Noticable inprovement
To complement the fuse,and best bang for buck I found signal cable makes a awg12 high purity Teflon,Copper digital cable that is outstanding used as a pre and is recommended .a12awg wire can handle 20 amps all day long
This pre is only 5 A. The tricked out unit I heard was every bit as good as any $4-5k unutI out there maybe not in all depts but in imaging,bass and sonic purity a SE pre is hard to beat,forget about the new price you will put $4/500 in modding counting $200 for the tubes for less then $1k total
A $4-5k pre limitations only 2 inputs.
