Weebl anyone?

[KShaft]

Has any one seen the circuit or a finished version of the Gilmore weebl.

Ive seen the blue hawaii(the revised tubed amp for electrostat headphones), but not the tubed dynamic amp(which I am assuming is named the "weebl" but I could be wrong).

Has anyone seen the above stated product?

Just curious...
k.s.

KS,

I think there is some confusion. Weebl and Blue Hawaii refer to the same amp. Weebl was coined by someone else, Blue Hawaii by KG himself. Both are the hybrid designed amp with solid state inputs and tubed outputs.

There are at least two members awaiting the arrival of their Weebls. One is coming from zzz in Canada to smokey in CA; the other is coming from Mikhail to bozebuttons in NY. Each has a slightly different twist with a transformer change in one; and a tube rectified power supply with BlackGate caps from the other.

Thank you for the clarification.

the blue hawaii is the electrostat amp correct?

was there ever a hybrid dynamic can amp?
I could have sworn there was, perhaps I am mistaken...

ja mata,

Pictures of my personal production units in a few weeks
depending on when the parts show up. I have the
circuit boards in house, and many of the parts on order.
Custom heat sinks may be as much as 6 weeks delivery.

There is a hybrid dynamic amp using 6c33's, but production
versions of that may not show up until very late this year.

All of these are units i'm building for myself and are not for
sale. Boards may be available in the future however.

One of the 5 blue hawaii units i'm building is planned to
be a demo unit mated to a scd-1 and may appear at future
meets in the chicago area.

Yes i really need 4 amps for myself. One for the main listening
environment, one for upstairs, one for downstairs, and one
for work.

I'm really looking forward to that Kevin!

Here is a high res (5 meg pixel) shot of the board
with the tube sockets.

It will be a welcome addition, I cannot wait to hear it. No plans have been made for the next meet but I am sure there will be something in the Spring. Maybe in the NW suburbs this time.

Thank you very much!

Id love to hear a BH! I doubt Ill get to though, depends on where it travels!

thanks again,
k.s.

Cool!!!

Now I just got to finish my KGSS quick so I can start building the Blue Hawaii...

Hell I got a lot of the parts for it already...

I just want to say that after 2.5 days of buying parts on the
web, even a small production run of these things is a daunting
task. Building one prototype was easy, building 5 production
units with perfect chassis, machined heatsinks, top quality
parts et all is quite a bit of work. Now i know why i stopped
building and selling amplifiers.

I still don't know how much i'm spending, but black gate
caps are about $500 per amp. Good tubes (as in NOS
mullard) i don't have a clue, as i already have a bunch.
I figure the parts cost could be a minimum of
$1500 per unit. And i expect to put in 30 to 40 hours
of labor per unit.

So the people out there building and selling them
good luck to you...

How big is that case Kevin? It looks like it's going to be a monster. Stupid question - Whay are the two center fins on the heat sinks shorter?

 

[kevin gilmore]

Its a two box thing. One is the amp, the other is the
power supply. Each box is 12 x 3 x 9.

It looks neater... Actually its the heatsinks i have the
most of. May change to bigger ones in the future.
Each heat sink pair dissipates 16 watts or so.

Kevin, I noticed that there are two 220 pF capacitors on your'e board that I think aren't on the original schematic. Have you made some changes to the design?
