Receives feedback from the output across the emitter resistors through R22 and R Logged ryansteele Chipper Posts: They will break with the slightest nick, and several disconnected themselves as I was replacing the IC with a socket. Ain’t happening either because bias is messed up. The thought was – is it really necessary to ground the heat sink?
I’m quite datashret the original circuit was meant to be something like this. Q11 and Q12 is a complementary Class B output stage. How can the base of Q6 be more negative i. The heat sink does carry the “mid-point” 30 volts and of course is not grounded. Please login or register. Up to this point I am somewhat satisfied. The fuse holder is secured to the side of the cab, the transformer and electrolytic secured to the bottom with nuts and bolts through the cab.
The diodes between the bases don’t confuse me, I’ve seen those too many times like Q7 and Q8.

I suppose someone did a hack job drawing this thing out. I want to perfboard build a clone of the entire amp, but I would hate to find out that the schematic is wrong.
Since the 2N is in a TO case and rated for 50 watts with a 2N complement it makes some sense since they may have to provide more current to drive less than 8 ohms of the single speaker versions. Getting rid of the mica washer which is both electric and thermal insulator is datashest beneficial.
If the input caps are showing something other than a value of “1”, refresh your browser.

Let me tell what I think about this circuit before I get to the problem as a mistake in my understanding may have something to do with how I got myself confused if this amp possibly works. It does seem to have an incomplete or maybe sloppy feel to it – the component numbers jump around, there are holes in the sequence, some components don’t have numbers just values. Hope this information is of use to someone.
So I’m assuming right now that I can find a suitable substitute using the 2N characteristics. So, either this circuit won’t work or I am totally not seeing something. The first transistor is the input, second the voltage amplifier.
July 30, The emitters and base are connected with wire wrapped around the pins and the other end laying on a trace, both ends soldered of course. This is the insides.
There are also holes in the boards left side in the picture where screws go through the case, through a round, roughly 1 inch long plastic spacer, through the board and a nut secures the screw at the bottom of the board.
The wood strips used for mounting the back panel are stapled to the sides of the back. I haven’t been able to find a datasheet or crossreference for these numbers.
I thought about getting a schematic for the “Dirt Road Special” as it should be basically the same amp. Everything else is so perfectly symmetrical with this circuit that this seems to stand out like a sore thumb, but I don’t know what to make of it other than to assume Q5 needs more voltage gain than Q6 for some reason. I’d say forget this circuit. They are mounted to the heat sink with screws on the bottom side of the board and secured with nuts.
I guess I don’t dwtasheet why that would lead to instability. The six TO transistors and the two TO-3s make up the power amp. From Q7 through Q12, the circuit is identical. There is no “chassis grounding” cap on the primary AC side, just the 1 amp fuse and switch.

I don’t understand that – during the early s Electro-Harmonix would sell you the amp in 2n368 form, so I would think there would be at least some dated before With the addition of this capacitor the amplifier actually begins to have some gain and that base datashret is also essential. Well, I run another sim: Just to prove my suspicions about this circuit datasjeet looks a bit messed up right I draw the damn thing on spice and ran a sim Almost, but not quite.
July 02, August 24, Might have some problems in reality that yo’d have to compensate, i. Hi, I am having a heck of a time trying to confirm at least in my mind if this power amp schematic works or not.
Since I have this Dirt Road Special apart, I thought someone might like to see how it’s put together. My only comment aside that and the issue 2 is the gain of
