where to buy the 6l6 se amp?

Elekit TU-879S 6L6GC

Actually, tubedepot sells ones with the 117v dual primaries: http://tubedepot.com/diy-ek-tu-879s.html

This might be alright, the universal tube amp pcb.

Push-pull KT88 class A amp with "universal" driver PCB

sigh..

2X DIY PCB Universal Push Pull Power Amp Board | eBay

I only need one! I'm not made of money...

OH I am a giddy goat, I'm going to need two if its going to be STEREO!

I think I could tackle that, the difficult part will be finding two chassis that are cheap enough, and transformers.

We have a go on:

Sowter 3575-C

But

The Sowter UA21 is a bit much:
SOWTER TYPE UA21 PP EL34 UL

182.35 GBP = 282.367 AUD each...

x2

= $564

$200 is my comfort zone for a good price for a single REALLY GOOD output transformer, beyond that and its getting a bit rediculous.

Don't think I'll build that pete millet one, sourcing a suitable power transformer/choke isn't in my expertise.

I'll go with the Elekit.

Thanks for your help everyone.

RE EL84 PP kit types:
You could use the Dynaco Z-565 output transformers from Triode Electronics @ $85 ea and the PS trans for $65 Tubes would be under $100 with JJ EL84's which are tough and would work well on most EL84 PP amps.

If you don't want to make your own chassis you could also use their chassis and complete ST-35 kit. It would also be a nice 17W/CH amp with the EFB mod mentioned.

Pete Millets Amp could be made to work with affordable Edcor PS and Chokes for the PS . It would give a very useful amount of power at close to 30W/CH

Just research the forms for more info. Google can be great. As for a diy chassis , use aluminium as it's easy to work with and put on a a simple wood base. Hammond also makes chassis with optional wood sides.

Just that the extra power will give you more headroom with more speakers. SE can suit different music than PP also.

Hmm if I do it I'd have to get the supplied chassis, something more fun than sweating over a hot power drill and lots of metal shavings.

The ST-70 kit looks very nice.

Hmm, I'll take a look at their site and think about it. Thanks for the heads up.

Hmm

I do love the 12AU7...

Tho I might have to make a Bridge rectifier adapter to swap out the 5AR4 if I don't like the sound with my type of music. (Fast paced)

Or even better install a switch inorder to switch between the two types, Silicon & Tube Rectifiers.

A nice read: http://www.tnt-audio.com/ampli/dynaco2e.html

The ST-120 looks even better....

tubes4hifi amplifier KITs page

Does anyone have a cheaper source?, I would really like to get underneath that $1,000 radar.

Might have to settle for the ST-35 anyway though because of power consumption issues :P

But my musical tastes beg for more power.

I can probably source a 5AR4 from my uncle... might even be a Mullard, a 12AU7 I've got in my back pocket, several infact, now I just need a pair of EF86's... then to buy a quad match set of JJ EL34's..

That right there would save me $129.95 now and make me spend $60 later on...

I don't really like JJ's anyway, I'd prefer EH tubes, dunno why I just like the funny looking face on the boxes/tubes.
