Question regarding 6J5 and 6SN7 tube usage

<< < (3/3)

steve:
For newbies,

For someone who wishes to create their own adapter, or switching for multiple tube types,
it is very difficult to design such without affecting the sonic qualities of the music.

Depending upon how critical one wishes to listen and compare, one must consider the extra
number of solder connections/terminations, type of solder, if used, extra pin connections and
materials involved, wire type and purity used, materials in general in switches; all will  influence
the sonic quality and signal degradation. 

A poor quality adapter or switching tube pin assignment will give a false impression, or misleading
sonic difference between different tube types that may not be accurate.

cheers

Response Audio:
You are absolutely correct Steve. Thank you for bringing this up. I don’t want to imply that using tube adapters is a proper way of doing things. When I do it, it is usually for testing purposes. The final design does not use adapters and always re-tested after using the proper tube socket for tube used.
I would never recommend a newbie attempt  to make their own tube adapters. One slight oversight and you chance damaging your build/product and possible bodily harm.

tmazz:
Oh yeah. Tube circuits do not use a simple 5v B+ rail.  :shock:

Get something wrong and things tend to go boom.
