Since I don't see myself hauling batteries to get an A class amplifier playing I was wondering about a PSU for the Hiraga monster.
I've seen them without input chokes and with. I believe the Lundahl 2733 was mentioned, also the 159ZG Hammond. This came about in an older thread but since I'm a beginner the discussion was a bit all over making it very hard to follow. From what I read the input choke is the better option for this amplifier since it can deliver large amount of current very fast. So maybe someone could shed some light on this and maybe a schematic. I think the discussion was also in l'audiophile magzine about the PSU for the 20W and they somehow changed it to have a choke in it but I couldn't find it for the life of me.

I don't want to interfere but to get a choke at the size you want will probably be that of an iron core. Iron cores store because of greater flux density energy in the iron for a long time (relatively) and make the amp sound sluggish. An aircore is much more costly but that is the only real option. Calculate the required induction
You need to do your research on using choke input powersupplies. You must follow the laws of electricity otherwise you run the risk of blowing up your amp. Lundhal has info on there website.by the way the xl of the choke required,it will need to be a metal core.
Really? I've had nothing but good results from choke input supplies, all currents and voltages.
There are huge differences in the design of transformers obviously. Some are very suitable as "chokes". I have an SE power amplifier (380 watt consumption) that I installed two transformers in series (C-L-C-L-C) as chokes. I use their primary winding to short-cut the inductances of the secondary windings used as "chokes": the difference is clearly audible. It is the switching between inductance and resistance, roughly.
But I don't recommend upgrading a Hiraga Classe A in this way, but going straight to SE. A Hiraga Classe A is a 4-stage complementary transistors pp concept. Audio or listen music at high level is NEVER achievable with it)-;

"Does the 30w Jean Hiraga Power Supply need an input choke coil?"
no, Jean Hiraga did not use a choke.
