Yes, I agree. If it were the amp, the distortion would be on the right channel, and would have been present on the swapped driver if that were the case, I would think.

Odd is right since it doesn't sound like driver distortion.

edit: check to see if the spider is loose.

Don't forget your amp was modded with Elna Silmic II 470uf 50V caps. They do make an improvement from stock in my opinion. Each cap (4 total) is $2.15 plus shipping.

Nice job assembling such a nice system without a huge outlay in costs!

Yes @cervelorider -- thanks for the link on those caps.

Anyone have any experience with this phono pre:
BHL Audio JFET Phono Preamplifier Kit 2SK170 RIAA | eBay

Could be powered off my 12v SLA battery for my TT. That would make for a clean signal path into the baffles...

Is there anything special about that BHL preamp? Seems awfully expensive for a pc board with a few jfets and caps. Can't this work?

How did you choose the TpA3122 amp from Jerry's Electronics? And how do you like it? Why is this better than a Sure prebuilt from PE? I am looking for a compact amp to put inside a speaker cabinet.

I have no experience with the Sure prebuilt from PE. The Jerry's Electronics with upgraded caps was a recommendation from @Cervelorider. I figured I'd give it a shot before jumping in a purchasing a SET. I am VERY happy with the sound and I love that I can battery power the whole thing.

@Cervelorider was very helpful in provided recommendations and selling me an amp with upgraded caps that he assembled. I am very grateful that he was willing to do that as I am not yet comfortable soldering a kit up like that yet.

Cervelorider can probably clarify then, but I imagine it has to be the quality of the input/output caps that makes a difference as the stock ones that come with the Sure are not the best for musicality. Looks like a fairly simple build though. An option is to replace caps on the Sure and save the build time.

I'll message you the differences (many) as I don't want to hijack danvprod's speaker thread. Btw, I will solder a 3112 board at no cost for anyone who wants one, but doesn't have the tools or desire to sling solder.
