That's, kinda terrifying. Is it just the 600 or could it possibly be other amps of the same era as well? How better would a CCS modded 600 perform to a CCS modded 006t btw?

okay so I tried jamming in a 6mm and does seem to be spring-held but it worked! and it turns on! And promptly burnt out the fuse in my step-down transformer... Well, that could be a number of things but the amp is just 45W right?

Sorry for necroing this thread but I got an SRA-8S, pretty much all original except for two switched out knobs. I plan on restoring it but Im stuck on a rather simple hurdle. The fuse, 5mmx20mm nor 6mmx30mm would fit. So what size fuses do these things use? It looks like a 6mmx20mm but as far as I can find, there is none

I'm very curious about the driver construction though. Are they actually going to make it like the original SR-X with a mesh stator? Quite looking forward to seeing more info on them coming out. Anyway I actually think it's a good decision for Stax, the L300 is... not good and Stax does have a neutral/pro headphone hole without the 207 anymore

It's announced, the SR-X1. So I was close with the name~

The SRM-2705 I think is the big clue since its probably a SRM-2xx. Why call it the 2705 though and not a 270S? Unless that 5 is an S but it looks too different

SRM-2705?

Ahh, that makes sense. The German market really got a lot of unusual stuff, I've seen a Gamma Pro New before too. That looks like a thinner cable than the SR-007, maybe same as the L500? A new entry level round Stax? I'll bet 20 bucks they call it the SR-X Mk 4

Huh, I was thinking its a Lambda Spirit but it still has the mineral wool of the Pro so that made me confused. People would buy it~ Heck if I had the money I'd buy it. I don't know why exactly but the idea of having a bucket of Lambda drivers amuses me

So there's a sellar that popped up that is selling A LOT of Stax parts, including a literal bucket of SR-404 drives. But this caught my eye. STAX A-PRO New Kopfhörer Teile | eBay A Lambda Pro New? I've never seen or heard of anything like that. Something in between the Pro and the Pro Classic/Spirit? No headband or cable available though.

Sorry for reviving the thread but don't know anywhere else in the site I can post this, got something curious. A Napolex NSA-3

Another longtime update. Going through the amp I found that pins 7 and 8 on the phono connector were already jumped. After more thinking and pounding my head, I realised that the ground for the for EVERYTHING but the power/bias section is actually coming out of the phono board connector. In the schematic the ground for PB-300, PB-200 and PB-100 were all connected together with the ground wire coming out of the PB-100 board. For some reason PB-500 ground was connected that of PB-200 instead of PB-100 but anyway. I just rewired so the ground connection is at the PB-200 connector instead leaving the PB-300 connector essentially unwired except for the MAG input. The amp is now working flawlessly and is silent than ever!

I've been pulling my hair with the damn phono board to the point I might as well rebuild the entire thing leaving only the film caps. Is there anyway to bypass the phono board in the amp? Without the phono board there's considerable hum.

A strange update, so rectifier and a few other diodes replaced and yeap! That strange warbling sound is gone. Except now there's a significant amount of distortion on all channels. After trying some stuff, removing the PB100 board seems to solve it. Since reading the schematic, I assume that the PB-100 is not exactly necessary is it? Since it only does the mag pu?

Right so apparently I didn't read enough. I found an old post by spritzer that said it worked find with his C-series SRM-1 Mk2 and meant for amps that didn't come with a jumper. Though mine isn't a c-series it didn't ship with a jumper but heck it should work. Tried it out and it powers on, no explosions, no burning, nothing. Plugged in a headphones AND there is still not audio. Though I have discovered that the normal bias does not energise at all whereelse the pro bias does, there's also a hissing sound too only from the pro bias. A quick voltage test from the rails show mid to upper 360V so it seems the voltage change has been a success. Given that the caps I used are rated at 400V, I think I may go find some new ones... My biggest worry though is the transformer is a goner so I'll test that out.
