Hey All, I have two Hiwatt speakers that I bought for a project some time ago. They needed to be reconed and my project never panned out. So, here we are..... One speaker does operate but the lead from the voice coil to the cone is frayed. The other speaker has an open voice coil. Speakers are model...

Here is the rest of the preamp portion. Note red highlights on drawing.

I've tried to draw out the circuit as I have traced it so far. There is some funny business going on elsewhere but not as extreme. One funny thing is that they put the P.I. in V4 and the last gain stage in V5

Wow, this may take some time to sort out. I've attached some pictures. Let me know if you need any other views. I'll leave the chassis out for a few days. I should say that the amp sounds great. It is dead quiet. It has some nice 'crunch' on either channel at 7 and above. Cheers, Mike http://i.imgur...

Hey All, I guess the title pretty much sums it up. I recently bought a '78 SA-112. It sounds great, quiet and responsive. Being the curious sort that I am, I decided to pull the chassis out and have a look at the insides. As I was looking at the back of the amp, I realized that there are 5 preamp tu...

Good advice I'm sure!

Thanks!

I found one. A '78 SA112. I can't wait to try it out.

Cheers, Mike

Hey All,

Hey All, I have a Hiwatt labeled Fane with the sticker missing. with a Purple Hiwatt label. There is a stamp on the frame in a circle that says 'Hi-F? and '4' underneath. The cone is stamped W5333 and underneath 426. The cone seems to be in exceptionally good shape (might be a re-cone) Any idea whic...

Hey All,

I have a chance to pick up a '72 Cabinet. I have been told that all 4 speakers are blown. Who would you recommend to re-cone these?

Cheers, Mike

Hey All, I have a Hiwatt labeled speaker that I pick up at a swap meet. I've been trying to find a match for it but haven't been successful. I believe this is an Eminence speaker labeled for Hiwatt. I email tech support at Eminence.... "It's not a Fane speaker. That is an OEM custom design that...
