Aleph J illustrated build guide

Hello,

After listening to the Aleph J version for a few days, I preferred the sound of the F4 version. For this reason I'm selling my assembled and tested boards (which are almost new). Bought on diy audio and mouser for components. Contact me privately if you're interested.

Thank you and have a nice day.

I desoldered Q2,3,4.
The desoldered Q3,4 (ZTX450) is NPN.
The desoldered Q2 (ZTX550) is NPN. woops.
These ZTXs seem to be fake.

I have ZTX795(PNP) and ZTX458(NPN).
Can I use these?

After a long period of browsing 500+page thread and rounds of searching keyword. Finally find someone encountered the exact same situation .:headbash:


The DC offset is too sensitive to adjust and impossible to get 0v result. Sadly I overestimated the ability of myself and did like triple check of soldering and every resistor on board. Then leave it on the floor for a week to take a break and clear my negative energy.

My ZTX550 is bought from ebay as well since it is out of stock everywhere. I checked the pins and turn out it is indeed a NPN fake one. :nod:


Mind blowing lol. It is not even an expensive component. I bought it for just few dollars, why would someone be interested to make a fake one. :nod: Anyway, waiting for new transistor now.
