wow ! lot of stuff there! can you please explain the pentode/triode switch option? I did not get much from the diagram, but by your comment interest me a lot!

I use an eq on the EF86 loop, and when I want to practice low volume I lower the level fader and it still sounds great. But I do this for practice, never done it as a one channel MV. Your idea seems interesting...

maybe you should try doing the whole section again?... I (somehow) glued my tolex into my amp, and had those problems too, I found the easiest way it's not to put some small drops, but redo a bigger part of the section. Maybe you shuold try to clean the inner part of the tolex, for the new glue sticks better. Remeber you must put glue (on tolex and wood), and wait about 5 minutes, the do hard pressure for better results....
Good luck!

The DC30 is very responsive to the picking dynamics. You'll be amazed of how easy you might get into that tone territory. The EF86 has an special magic for that kind of tones, thoug the Treble boost channel does them pretty well.

well I tried it... and could not keep for more than 5 minutes... the small room, the other guys complaining... the amp SOOO loud.... It worked beautiful, but it's too damn3d loud!

well... yes... after all we are looking for bedroom solutions, somehow you will sacrifice some tone on the quest. As you said, the dc it's an must-crank amp. I've been trying some very low MV with a boost, and it's been delivering good for late practice at home. But sill I'm curious about the PS, it's something you may need to tame the amp at rehearsal or gigs in small places. My last gigs have seen my amp at 9:00 or less, at lo power. I can see the sound guy going crazy when I attemp to get more gain from the amp and not from pedals...

Tomorrow night I'll try a couple of changes in my setup... I plan to try the amp at 12 or close to, and use an compressor to cut the signal at half or so for cleaner settings, no compressor for stronger rythm and sd1/808 for solos... Tell you about it later!
If results are as expected, some PS may be needed, because MV will damage my tone, I've tried before at higher volume settings and thins too much...

Excelent!
And what about gain and crunch? on lower PS settings, you can crank the EF86 and get higher gain sounds at lower volume? Does your old EF86 got microphonic when you cranked it even at low PS settings, or was it just at blast?
Regards!

I see... So this is not like a load for the speaker or alike... it works before the speaker out jack... Another question -I may be hijacking my own thread!-  Once you install this PS it will always be engaged? or it is some how bypassable if you want it to? or is it like MV that on 100% is bypassed?

As far as I understand, this PS won't short life on your EL84's as a Hotplate would, because it works "inside" the circuit and not as an outside load. Please correct me if I'm getting it wrong.

Thanks for your answers and patience!

Does this change of rectifyng type requieres any adittional mod to the amp? Or is it just turn off/change them/turn on?

would this Groove Tubes do the same job?

Thanks in advance, I'm really tempted to do this mod, as I have read from your experience. I barely tweak my amp, I love just like it is, but now you guys tempted me!

Once you play an EL84 amp you inmdiatedly fall in love with them... there is something to them that is magical. Even my Paevey Minicolosal (1 12ax7 1 EL84) that is capable of higher gain sounds, have this magic and  the powersponge attenuator does a nice job.
I am a newbie here, how does the powerscaling works? I saw the kits and they seem really "simple" if you compare to an attenuator...

I was at rehearsal last night, I tried the EF86 about 10 o'clock volume, and it was simply amazing. But I still use an sd1/808 to boost it, so I guess that's my luck. Of course I could not get higher volumes, we were on a small room and my amp+drums its a real freq fight on the air!
Gotta try it on higher settings without the pedal, I've found amazingly better than nothing, shame on me I always relied on pedals! I guess I should be scoring for one of those mullards....

 
I'll be waiting!

It's your DC30 a combo? Mine is a head, and as I said I've been lucky with my EF86. But also, I usually run the amp on half power and volume not past 9:00, so I am not demanding too much from her...This channel is real loud anyway!  A couple of days ago I did an outdoors gig, and again, the sound guy asked me to lower my volume (it was below 9:00!)...
Do you use any pedal for gain? or just the amp crancked?

hehe... I know what you mean....take your time. But as soon as you can test it let me know...

I've been so lucky with my EH supplied by Nik. I live in Costa Rica, so my local option limits to some Sovteks I've found on an electronics store. I also have another EH replacement, but untested.
So did you find the sound of the new EF806 somehow similar to the EH? volume, etc?
