The original SVT used a different driver tube that was well specified

** The 12BH7 - as previously noted.

The current production is a St. Louis Music/Gene Kornblum bodge. Done as
cheaply as possible.

** The SVT-2 Pro retails here for a cool $A 5500.

The amp is full of crappy dodges that no tube instrument amp should ever
have.

Eg :

Ribbon cables with IDC plugs connect grid bias to all the OP tubes.

Phil, the Chinese invasion is all but complete,
and mopping up operations are underway for the period of occupation for
the
forseeable future.

Nearly all musician amps are now festooned with all manner of effects
boards and do-dah switches
for gee-whiz effects to make up for the lack of any real playing skills
of performers and the
godawful meningless lyrics of the songs being sung.
The medium is the message now.

In many amps there are second generation PCBs with circuitry full of
tiny opamps and surface mount parts and one dare not try to repair
anything
except by replacing a whole board, but unhitching the ribbon cabling
and installing a new board, and plugging cables back.
Somehow I get the feeling that NONE of what is made now when
ppl of 20 turn 60 in 2048 will have any collector value at all.
Who will treasure a CP player in 2048?
Who will undertsand how one works?
Who will be able to repair a CD player?
Same will go for the thousands of guitar amps now made.

A computer with enormous complexity is remarkably reliable,
but in guitar amps and other gear consumers are treated like suckers.
Just about all electronics is passe, outdated, obsolete well before it
"wears out".

A late model Behringer combo amp I have here for repair is made in China
to a standard enforced by Germans. $399 retail here.
Lotsa features, and it does nearly everything except give a BJ.

But why the *** is this stuff in my workshop for a fix?

They just don't think of everything they should have.
Like, if there is a way a dude can *** it up, the dude will find a way,
even when he isn't tryin.

But the really bright electronics designer folks wouldn't be
seen dead designing guitar amps; no kudos. Only dumb counts
design such lowly crap, one step up from a toaster.

Its impossible for any one of us to have the slightest effect on the
quality
of globally produced kraperology.
They will all do it *their way*, and not ours.
Its always been that way.
