However, there is an asterisk by Q9 and Q10 and a note that Q9 is replaced with a 2N for the amps using more than one speaker. Getting rid of the mica washer which is both electric and thermal insulator is also beneficial. 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. I felt it appropriate to add further information regarding the transistors used in the EH Mike Matthews Freedom Amplifier here for this reason.

The “rats nest” of wires tie the power supply to the circuit boards. If you say theory and practice don’t agree you haven’t applied enough theory.

I’ve done lots of research datsheet the last two weeks and this is driving me nuts. Since it was too small I had to blow it up multiple ways to get the circuit values.

There datsaheet quite a few other connections made with wire soldered to the top of traces. 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. The six TO transistors and the two TO-3s make up the power amp.

You don’t need to datasneet the heatsink if you’re sure it cannot be shorted. The bases of input transistors shoud be biased to a proper DC potential – I don’t see it happening.

Of the two circuit boards, the smaller one at the bottom is the Small Stone phaser effect. Logged ryansteele Chipper Posts: The diodes between the bases don’t confuse me, I’ve seen those too many times like Q7 and Q8. Well obviously an input amp.

Q5 and Q6 also have 2nn3568 work as a phase inverter for the push-pull drive to Q7 and Q8. Receives feedback from the output across the emitter resistors through R22 and R What totally confuses me is the lack of a DC path to establish the bias. I think my assumption is a voltage reference. The wood strips used for mounting the back panel are stapled to the sides of the back.

Datashedt 02, Like the new look?

Notice the and dates. How can the base of Q6 be more negative i. So, either this circuit won’t work or I am totally not seeing something. In fact, some copper mounting clamps that attach transistors to the heatsink may serve as a wondeful supply rail. I understand that this will set the bias between the two transistors at three diode voltage drops. Three wires are separate grounds all coming off the main amplifier board.

What is causing my problem is Q5 and Q6 – how are they biased? I was getting together a parts list to build this amp when I noticed something that got me to thinking.

Hi, I am having a heck of a time trying to confirm at least datashewt my mind if this power amp schematic works or not. Yes, the transistors are original and still working fine and I won’t be replacing them.

The collectors of the output transistors are tied together. There is no “chassis grounding” cap on the primary AC side, just the 1 amp fuse and switch.
