Decware MODEL SE84C-DIY

[gni]

At last, a DIY Kit from Decware that's affordable! Only $299

Some changes from the regular SE84C:

Solid State rectification Vs Tube rectification

Circuit board Vs Point-to-Point wiring

Assembly instructions lack some important steps
but okay for those with tube amp building experience.

The assembly instructions also include specs from the
standard model including wording stating that the unit
is point-to-point wired while it is a circuit board model.

Looking forward to seeing other opinions on the newest
entry into the kit tube amps.

The "iron" in these kits is very good!

That is good to hear that the iron is good. . . custom made
should be good. . .most expensive part of the price.

So that's what the missing tube is eh?

I don't see a problem with that. I like diodes better anyways.

Not bad for the money, a bit cheaper than Bottlehead's offering.

Let the cheap tube kit amp wars begin!

[gni]

I agree. . .cheaper kits would be nice. . .since most of the cost
is usually in the labor supplied by the buyer. Unless it is very
special iron in the transformers.

Solid state rectifiers are just as easy to change out as a tube
rectifier; they drop less voltage and run cooler.

$223 + case/power cord/feet/RCAs/Binding Posts/board would
probably be more than $300.

Steve has put together a great kit. It includes the
board but lacks the tubes. . .so Steve's kit would be close
to $400 with tubes and shipping!
