Iam planning to use 6c45 as a input tube for a ss amp SE.
But I Wonder how Hard I should driver it.
Im thinking 20 to 30mA , or is it any benefit
In going to 40mA?

I'm not currently using one but have played around with one and a colleague has used it for many years. The thing that I would be looking at is more 'subjective sound' than about power dissipation vs life. There are people who have used these tubes and found them a little harsh. I've had more experience with it's brother, the 6E5P tetrode which when triode-wired is a similar beast. it seems that a number of users have found that the subjective sound is not optimal at all currents and you may want to keep some flexibility in your design in case there is a sweet spot for your implementation. And I don't think it's all about harsh = parasitic oscillations, it's more than that.
100k as anode load??? 😳
6C45P output impedance is 1155R, so even 5k load is perfect.
If you see the tube curves and knows the desired anode swing, the operating point easy to select.
For maximizing the output swing (VAS stage) the choosable anode range is limited, about between 10-30mA.

If I see correctly, this amp requires only 11V peek input.
It's not high gm tubes territory, any tube capable to produce 22Vpp swing.
IMHO better choice 6-8x gain capable low output impedance tube.

A noob question about induktor.
Lets say I have an induktor 30H/40mA.
Do I have to run 40mA trough it?
What happends if I use sayy 20mA trough it?

I see a lot of People writing that the 6c45 sounding hars.
So I m thinking of going with the 6e5p
Imstead..
Comments on that...

I see that on the datasheet it says that 6E5P has a service life guarantiee of only 500h,is that correct?
Maybe i should use the 6E6P instead wich has a lifetime of 10000h...

Any one been using the 6e5p for a "long" time and can comment on the lite time?
500h seems rather shorts...

In found this link ssying that at 200v 6e5p has an amplifying at 50.. is thid True,?

I thought so,I am at the moment leaning towards using 6E5P.
As people are are saying they are very transparant and have used them for several years.

As a gain stage 150V anode 20mA works quite well in my experience. I’d use a cascode depleteion mode mosfet CCS as a load. I have used a 70H choke and like the CCS load better. Diodes for cathode bias, between 1.5 to 2V. I’ve also run them at 175V 40mA in a PO class A spud and they sound wonderful there too.
