Hi everybody! 🙂 ,
Is first time when I write here even I read many threads.
I intend to make one single ended power with GMI 30 at 3Kv in anode.
Driver I will use 300B with choke in anode (500v).
First tube will be 300b (mesh from EML) or 20B.....
All stages with auto-bias (even GMI 30).....I like sound of this type.
I intend to make power with two transformers 2x1500v each and two GG1 0.5/5 for each transformer. I will use 2xAMCC 500 Hitachi.
Will be with CLC 5uf - 20H (500mA) - 300uf/1800v.
My question is; anybody test this GG1 rectifier (how is the sound? ),
of course I can use EY500 but I wish something stronger.
Some people say good words about gas rectifier others no.
For the moment I test this amplifier at 1000v and sound is very good with GMI vs 211 or 845.
Is other league, other sound ....even at 1000v.
A good tube to compare is 833 and I will do this in near future.
I forget to say, all transformers and choke is made in house on Hitachi AMCC core, just double C (like Lundahl ).
For cathode resistor I use many TKD 2W , but here I have other question;
very good electrolytic like Kaisei bipolar or classic PPR, because good PPR over 100uf is not or very hard to make(insane expensive).Of course is 0,01 and 0,1 for bypass.....question is the big one 🙂
