Aleph J build guide for noobs

[getgoin]

OK. first channel bias and offset successfully set.

Do same for other side?

 

[Zen Mod]

yup

 

[getgoin]

OK. fsecond channel bias and offset successfully set

 

[Zen Mod]

ok, wire inputs, arrange SE or Bal properly, connect speakers and source, listen

 

[getgoin]

arrange SE or Bal properly

Dont know "SE" or "BAL" so arranging them would be a total guess.

 

[Zen Mod]

which connection you have on back panel, RCA or XLR or both?

 

[getgoin]

Only rca

Hi Getgoin - Looks like ZM is taking a very rare break for sleep.

I'd encourage you to follow the guide directly. It shows connection-by-connection / measurement-by-measurement how to do the final setup for your amp. Of course, if you have more questions, just post. However, everything is already written in a very nice format with pictures.

Congrats on getting both channels' bias and and offset set! Nice!

on channel pcb - short -IN with GND, in easiest way for you ; shorting wire on Euro blok is OK

I hate anything which isn't soldering on audio pcbs, but - hey - that's just me

route twisted pair of wires from input GND and + Input to input RCA, ring GND, center +

Voila!

It is done and hooked up to system. My gosh! It i so clear, present and transparent. Even the silences between notes are musical. Spent most of the day yesterday listening and grinning. The Aleph J is part of a three way upgrade for me: speakers, amp and preamp (all DIY). All three are done and each made a significant contribution. The preamp is the Korg B1. I have a slight intermittent issue with the Korg (I think it's the Korg): very high pitched tone. Maybe microphonics. Anyway, I'll post this over on the Korg preamp thread.

Thanks Zen Mod and ItsAllInMyHead for sticking it out with me. Your help made the difference.

Here's what it looks like all hooked up.

Aren't you a Heresy guy? These aren't Klipsches but they are supposedly close, a cross between Cornwalls and La Scalas.

The Aleph J is a remarkably clear and musical sounding amp. A rare combination, with few peers in those aspects. The M2(x) is among its peers.
Twenty hours is just enough time to get a sense of the amp's sound. Give it 100 hours to fully run in, and smile.

I am Heresy Guy, in principle and everything

though, my present living arrangements are not allowing neither Klipsh Horns nor Jubilees, and these are only one I'm interested in

So, content with small (refrigerator) sized MLTLs with dual concentrics, for now

Congratulations on your AJ build!

The Korg tube can be microphonic so please definitely check the Korg B1 thread to get some suggestions on how to mitigate this.

Am I going to regret using the Panasonic 667-eeu-fm1v221 for C2 and C3? The boards are done but not on the heat sinks yet so I have time to change them if it will really make a difference.

 

[Zen Mod]

just chill

How about cat 6 for the input wiring? I see reference to it in the f6 thread. Maybe for the speaker connections too?
What I have is not solid core though.

 

[TungstenAudio]

CAT6 is great for input wiring.
Not recommended for speaker connections, way too thin.

 

[Mulburg]

Thanks. I’ll have to dig up some solid core.
