AION RIFT - SUPAFUZZ - ADDITIONNAL EMITTER HOLE ?

[zubi]

Hi everyone,

I've almost finished soldering my AION's rift (supafuzz)
but there's a hole for, it seems to be,  an additional "E"mitter on the left of each tranny socket of the pcb.




I cannot figure out what it is for ...
The installation guide does not mention it.



Thanks for the help.

welcome to the forum. and an easy peasy to start out. the most common transistor outlines/packages are E/B/C [or its reverse - C/B/E] and E/C/B, which we often call end-base pinout. if you look really closely you will see ..... I dunno. wait a minute - what part number transistors are you using on that build?

it is polite to post all your build docs, or links to the docs, when asking for help so's we don't all waste time talking about the wrong things - V1.1 or Legacy, like that.
******* Aion, if you are watching, would it be possible to include this point in your Where to get help section of future manuals/revisions?

Thank you duck_arse for your wise comments.

It uses only regular trannies: 2N3903 and 2N3904

Here's the pcb where it is easier to see the point:



So for each transistor we have those holes E,C,b and E again.
I assume it s more logical to solder the three on the rigth ....

Hi & Welcome..

The three on the right are just fine..
You also have correctly placed trasistors facing up..

As the Rift is a clone of the Univox Super Fuzz (not to be confused with the Supa Fuzz as in the Marshall/Tone Bender Mk II et al), Aion mentions in the furnished materials that the transistors in the original units were parts such as the 2SC828, 2SC537, or 2SC539, all of which have the "end-base" pinout which our esteemed Duck described above. I imagine that Aion provided that layout as a convenience for builders who wanted to use original-spec transistors or similar. (I myself have had excellent results using PNP 2N3703 transistors which also use this pinout.) Honestly I wish more PCBs used this layout for BJTs!

Thanks a lot guys

E and E are both connected via a track, was what I was going to say. so you have E/C/B/E, allowing E/C/B and a shift to C/B/E, see.
