dumb question :P KT88...

[firefart_1st]

i need to clear one thingy

on a push pull amp with 4 KT88

the output transformer will be 2.25Kohm pp ? right ?

after a repply i'll tell why i'm asking this...

According to the data sheets, this might be ideal if you are using fixed bias on a tetrode or ultra-linear configuration, with a 560V B+.

 

[firefart_1st]

it's an 560V supply.
and its and weird amp that was not working right and and friend of mine sent it to me.
the output transformer is near 8K pp
thats why i asked...
like that the amp has low power and distorts when puted loud.
fixed bias it is too.

i think its an hiwatt like power amp. and the preamp is somewere and vox or an fender...

its a total custom amp but not done right

So watcha gonna do with it?

 

[firefart_1st]

i'm gonna change the OT to an 2.25K with 2 4 8 and 16 Ohm output ...

i have a local man to make that

then ill test it up.

the owner said that like the tone of that amp and wants it to work the best.

i said to him if we want connect a 4 ohm speaker on tha 8 ohm out or even on the 16 ohm output. i dont guaranti itts good but. until the OT is made and paid o wont mess with that amp.

its an 200W monster !

bass or (clean) guitar

i was feeling dumb about that OT...
a tough i was wrong when reading that datasheets

I used to run PP 6550's at around 100Wpc. I did some good listening with that amp. I have read about 250W from PP KT88's. It was described as sounding effortless, like there was unlimited power.

'unlimited power' sounds good to my ears.

but no so good for my speakers
