Hello again guys,
For those of you that have followed my meanderings on upgrading my Decware amp, I've decided to split the project into two phases. The second phase will be the fully decked and tricked SE EL84, with an EF86 input stage,transformer coupled, and with a super duper power supply. However, after starting to read Rozenbilt and Morgon Jones, I've got a good year of studying to do before I'm comfortable tackling that project. However, there is no way I'm not going to sling some serious solder before then. So now comes phase one.
I will upgrade my current SE84CSEX as follows. Both grid stoppers(330 and 1K) will be 330 ohm Shinkohs, The coupling cap will be a Mundorf silver/gold, cathode bias on sv83 will be kiwame, on 6922 will be riken. the 47k plates and 330k grid leaks will be rikens. The 100k pot goes, replaced with a Riken(value tbd). All the PSU caps will be ASC oil caps. The 40 uf will be replaced as is, the two 20 ufs with a single 10 uf, and the two 3.3s with 4 uf caps. I'm figuring the sonic priorities are first the coupling cap, then the grid stoppers,then the cathode bias resistors, then the PS, then the plate resistors, then the grid leaks. So heres the question.
Clearly, it would be easier(and safer) to do everything at once. However, if it would be helpful to you guys, I would do each upgrade separately and report on what I heard from each step.
So, let me know what you all think. If noone cares, I'll do it all at once and of course report back. If there's an interest, I'll do it piece by piece and report back. Let me know your preference and also what you think the modification order should be. I would probably do the PS caps last, as that will require chassis modifications.
Thanks, Bill
