Hello All,
From what i can tell he is talking about a tube amp with KT88's,
this may be a subject better served in the valve amp forum.
Unless Boboo can supply us with a better description or schematic
there are a few of us that swing both ways(tubes or solid state that is)...

Yes you are completely right but I’m a newcomer and did not know how the system works and my problem goes to both ways! Solid and soft!

The question or the story is this
I don’t know what it is but something is very mysterious with this Harman. ?????
I have tried to replace it during many years now and listen to lots junks, both with high end amps and receivers like Technics, Sony's Akai's Revox's , Sharp's Sansui's and you name it they were all in my living room on try but no one comes near by.
Is that somebody outthere who can tell me why? Because this guy drives all this and you can also see the pic above with out any problem at all..
In one channel for example I got 2x15" bass split in to two, very low so called air suspension cabinet and high bass closed cabinet.
Than, you got two drivers in a wooden horn low and high come in different size with 2 x 4" which overlap the two drivers and just for coloring the sound.
On the top there is one JBL 075 and four Piezzo discount.
Now the other side is almost the same but there is one 15" sitting in one big cube very low frequented faced to the flour to balance and colour the other sides air suspension cabinets sound. I got a very rich sound! That’s why it’s so difficult to find other amps because I’m loosing it.
I’m an artist and photographer and very sensitive when it comes to sound. Now I brought this heater to amp (yaoin) weights six times as much as a Harman and there is no bass it’s like a sopranos comparing to the Harman. The bass from the Harman moves like hell my glasses shaking and dancing in the kitchen and just looked what I got.
And one little question to all the solid state people. Help me please to refurbish my Harman.
I need those things like selector switch urgently. Check it out on the pic
There is some things written on the switch but it’s deep inside in the case.
It says PCB147F 94VI than bottom I think it’s just marking the position and finally some additional figures like 4551-7156
The selector had am, fm, aux1, aux2, phono1, phono2,
But if any of you can supply me with volume, ballance and treble would be nice too.
