Quality of S5's K-12G in proposed system

[xxguitarist]

I saw some threads on the K-12G, but nothing specifically speaking of the audio quality.
Is this a reasonable choice for setting up a low-level "audiophile" type system? I'm not looking for "reference" quality, but I sure want a good improvement from my sony 3 disc changer all-in-one-box model mhc-gx40

I intend to build some ported loudspeakers using a 3'' driver (or thereabouts) and use the much debated playstation1 model 1001 as the input, at least for the time being.

I expect to have a slight lack of bass, but really want some clearer mids & highs. Nice midbass would be good, too but I suspect that's more a characteristic of my speakers.

Thanks for the input

Bueller?
Anyone?

K-12G?

Whut de **** you talking about?

Perhaps you should explain/describe a bit more thoroughly, if you want some kind of answer.

Best Aloha,

I said S5's K-12G, maybe these amplifiers aren't as common on this board as others.

The current speaker plan is either the single or double bass reflex cabinet as shown here, with the FE127E drivers

These kit's have been discussed extensively. Run a search for more details, but basically they are a really good bang for the buck. I have a K-502, which is it's predasessor(it may still be available from www.tubesandmore.com). The sound will spank your sony boom-box internal amplifier.

Of course there are other options, but there are no other kit's in that price range. Though you may also be able to pick up a vintage tube amp in need of some restoration for the same price. You can't really go wrong either way.

Thanks jeb.
I actually placed my order last night- looking forward to it!

I am planning on one of the two designs for the FE127E drivers, as above.

Does anyone know the results of using 6ohm speakers to test everything out before I build the actual speakers for it? I have some sitting around, but It seems to be designed for an 8ohm driver.

Hi guys,
Got my kit today- already half done! It took the short side of 2 hours to read the instructions twice, check off the components, and solder all the resistors/caps/tube bases on the board.

Looking for input on mounting the volume control elsewhere.
Is it OK to use some 12G hookup wire to allow me to mount it to any part of the chassis? Don't want to create extra noise by doing something like that.
I've built the board with every component save the tube holders & the DB1 chip on the bottom, so I can mount it with the tubes sticking through the top. Doesn't work very well for me to have the volume knob awkwardly sticking out like that.
Same question for the input & output jacks. 12g wire ok to the back of the chassis that I'll build for both?

Also, I don't expect to need to, but could I extend the transformer's wires with the same?


Oh, and is it OK to touch the tubes with bare fingers? I know some car headlight bulbs don't do well with the oils from your hands. Not sure how hot the tubes get.

Thanks again.

Finished it up today, Very happy!

There are a lot of FE127 designs that are a whole lot better than the factory BR boxes you've linked too. Nice driver to work with and can get a whole lot better with a little attention.
