YBA-1A
YBA-1A
i just acquired this amp as a gift. great condition and loud as hell.
Trouble is, i plug into the amp and even with the volume ALL the way
down i can STILL hear the guitar thru the amp!!! i cant really play it
louder than 1 although i had it up to two one afternoon. its in the
basement and im the superintendent!! playing it thru a peavey 412ms
with celestion g12k85 speakers at 16 ohms wiring. is there anything i
can to do to better the volume sweep? also, at what point would this
thing naturally distort? when the walls fall down?!? jesus, 90 watts
from 2 el34's, pete was a genius. this thing is built like a tank.
thanx in advance for your anticipated assistance.

Don't try to get it loud with that 16 ohm cab....that amp wants to see
an 8 ohm load. I think that cab has the stereo/mono switch on the
back. If so set it to stereo and just use one side. You'll only have
half the speakers working but it will be safe to use with the amp and
reduce the risk of damage to the output section.

Re: YBA-1A
They are loud amps, and the volume pot gets loud fast. The best thing I can
suggest is to get an attenuator. t will let you turn up the volume pot
without knocking down the walls.

i also aquired an enormous bass bottom , ported enclosure for an 18"
bass speaker. i plan to run the speaker from the yba-1a head. might as
well, a champ 12 in excellent condition fell right into my lap and
sounds much better for what im doing. what would be a good speaker
for that ported giant cab? it must be 8 ohms as thre head puts out 8
and boardjunkie posted that my amp really is looking for an 8 ohm load
not the 16 ive been using.
brings me to another question......when deling with loads and tube
amps, whats the rule, i can drop the ohms to 4 in thtis case and be
fine but if i go up then i do the damage. i know also that placing too
low a load on the amp is dagerous. exactly why you cant leave it with
no load. blows the tranny or something i heard. get back to me, i
depend on you guys. and thanx

Its better to go down a step than up, but its best to have the load
matched to what the transformer secondary/selected tap is looking for.
No load is bad mojo, yes. AC Voltage from the output tubes goes into
the primary winding of the output transformer, then gets magnetically
coupled to the secondary winding for a lower voltage/higher current
output which is absorbed by the speaker load. Remove the speaker load
and the whole system gets unbalanced, to simplify a bit. The output
tubes don't stop working into the primary, and that voltage needs to
go somewhere...'specially the highest voltage transients generated by
a clipping (driven into distortion) output section. If there's no
load, voltage finds the next best thing... . it can arc over a tube
socket, ruining both the tube and the socket....or the output
transformer primary shorts between windings or opens up (melts a
section of the winding like a blown fuse).
Get the picture?

definately understood. there is a ext speaker jack so would i be okay
if i put a 16 ohm into each jack for total 8 speakers full stack into
8 ohms? i dont know if the jack is series or parallel. never did
remember the concept.
how aout my 18 woofer question? i dont wanna break the bank for a
speaker. i imagine that head in a 18 bass bottom 5 foot high would
kick @$$!!!

2 16 ohm loads is fine, the jacks are parallel. Regarding using an 18"
