Default Breadbox Gainclone

I finally rewired my Gainclone (previously referred to as the "Ghettoclone") and found a more suitable enclosure.

The breadbox was the perfect size. I am able to house the entire amplifier (transformers and all) in one box .

Thanks to all for the encouragement and the guidance. I'm really happy with the amp-- I think it sounds great. Now all I need is a line stage preamp. Any suggestions?

Kofi

Was the choice DPST or SPDT or NPNT (no poles-no throws!)? Looks very nice. Now all you have to work on are the interconnects and the speaker wires. Shame on you!

The bread box is VERY COOL!

Well... I have to admint that I went with the SPST-- just lazy.

Yes, I know I need good interconnects and speaker wires, but I gotta get through one thing at a time. Besides, Mrs. Annan needs me to help her with her knitting blog.

Ain't that emasculating?

Since you mentioned it, what would you recommend for cheap(er) interconnects and / or good speaker wire? I would gladly make some myself (I've been to the TNT Audio site and it doesn't look too hard), but I'm not certain that purchasing the damn things wouldn't be cheaper and easier?

Any thoughts?

Kofi

After a brief review of you cabling, might I sugest that Romex would be an improvement. Perhaps you could have Mrs. A knit up something out of some UTP. (Don't mention a word to anybody, but I am using the cheapest Monster cables that come with the gold plated RCA's). I think they're just fine. Cetainly better than those free turds (featured above) that come with the $49.95 VCR. Someday (perhaps after a felony conviction in an effort to do "good time") I'll braid my own speaker cables. I'm just not quite that lonely and bored yet.

If bored and lonely is a requirement for DIY interconnects then, HERE COMES KOFI!

Digi, your circuit looks a lot neater than mine. You'll notice that I did not include pictures of my wiring. This is by design.

Anyway, I'm sure that this question has already been asked and answered somewhere on this forum, but I'll ask anyway. Do speaker / interconnect cables really make a big difference?

Please bear in mind that I have recently moved my feedback resistor, input caps and filter caps closer to the chip and I have not noted any difference in the sound (however, I have noticed that all but the slightest amount of buzz has disappeared)... so maybe the question is this:

Will someone with an ear unaccustomed to subtle nuance be able to tell the difference between good cables and found-at-a-yard-sale-and-manufactured-by-Radio-Shack cables?

Also, for speaker cables, what do you use? I just have speaker cable that's called "speaker cable".

Kofi

Also, any suggestions for a line stage preamp? I'd like to start building one soon.

I have 8 ohm speakers and the GC has +/- 18V power supply.

Thanks in advance.
