There is no end; build them all.

You tempt me to try and list my projects (though not here, so as not to hijack)...

One day this thread will grow up and be a sticky thread

 

[Zen Mod]

hardly, too long and too wavy

as it needs to be ....

I like this approach. Gives builders a nice at-a-glance and an easy to find reference.

Can I ask what is the difference between

Choked Singing Bush ..... special one for Purists and Masochists and

Warbler MOS Schade MOS SIT choke loaded follower power amp

if I am going to use the THF-51S ?

Thanks.

 

[Zen Mod]

Choked Singing Bush - amp with voltage gain, having a choke as SIT Drain load (instead of Mu Follower, as in Singing Bush)

Warbler - amp without voltage gain, having a choke as SIT Source load, so entire amp being Source follower

now - as title of CSB sez - beware

Warbler needing less critical choke, SIT having much lesser effective Rout loaded at Source, so demanding choke of not so big inductance and Rdc of it less critical

I have no intention of selling kits for Choked Singing Bush; I reckon there will be practically 0 interest

in fact , will post Gerbers in thread so Masochists are welcome to do it on its own

 

[SPWONG]

If I use THF-51S, can I get around 40W to 50W in both Choked Singing Bush and Warbler Amp?

Thanks.

 

[Zen Mod]

yes, in both cases

say 35Vdc rail, say 3A2 Iq

though, as I said , going CSB route - best to have capable Winder guy as very close personal friend

 

[SPWONG]

Last question, in term of sound, which one is better?

Thanks.

 

[Zen Mod]

CSB is wilder, showing more of SIT character, euphonic

follower ...... more polite, due to lesser THD; take in account that it can be made with IXYS Pucks too

so, can't say which one is better - that's matter of one's taste

...... personal friend

well, that's sentence of the day

I prefer your comment about boutique transformers/chokes made by beautiful virgins on the full moon nigh (presumably naked) - that your Winder is not beautiful nor virgin, but winds very fine transformers.

 

[Zen Mod]

that would be - Winder, personal friend, with benefits

...selling kits... ...interest...

Hi ZM, if I may. Are any of your SIT amp topologies considered current source?
