Show us your flea-watts amps!

A little bit of Chicago Iron...

Thought I'd toss in a photo of my Grommes 221's..

flea watt amps

Well, those look very nice, but they look like they have more than flea watts, how many watts are they really.
Did you build the boxes that cover the transformers, are the boxes for some kind of shielding or are they to make the design look clean.

Here are a couple I've done: A 12AT7/12B4A, and a 12SL7/1626 Darling built on the diytube board (the purple one). The 12AT7/12B4A is just the Darling circuit point-to-point wired with the different tubes (with thanks to Ed Brown at diytube for writing about doing this to the Darling).

This is an amp I built in 2010 and has become my main amp.
Single ended 2A3 triodes driven by 6C6 pentodes, cap coupled and tube rectified. Puts out about 3 or 4 watts.

I am very happy with my fully rebuilt Scott 299B putting out a full 5W in triode mode. This amp was an experimentor's derelict test mule before I started my rebuild. The big holes in the deck were where a couple of UTC A-18 transformers were mounted; individual bias was provided for each tube so you see the pots are still there but no longer in use. The amp now has the "El Cheapo" circuit and a totally new choke input power supply with three chokes. There is a single input for each channel and high quality binding posts to connect "real world" cables.

Current iteration of the amp previously known as "Stancfish".

"Super" 6BG6GAs running P-P triode mode for ~7 wpc.

Being used with a pair of Altec Bolero.

Cool stuff guys. :yes:

The old Rotel single ended receiver.

 

[chinacave]

1st scratch build, SET Darling w/ lots of local AK help. All 750 milliwatts. Sounds fantastic.

 

[jsax420]

Hasn't made it out of breadboard yet, but this is a tiny SE amp with Russian subminiatures, 6p30b-r pentodes and a 6n16-b preamp tube. The 6n16-b is a little over an inch tall, the 6p30b-r's are about an inch and a half. I think it puts out around half a watt per channel.

 

[eratosthenes]

I have two that fit the description.

One is my ~5w SEP EL84. A Zenith chassis, pulled and modified into a standalone. There are 5-way binding posts and an IEC power socket in the back.



The other is my Bottlehead SEX 6DN7. I have the constant current source mods. I plan to upgrade the iron eventually.

45 mono blocks 2W under

These are 45 mono block sets that I built for my friend and I.

 

[jaymanaa]

You guys are killin me. I wonder what my wife would say if she came home from work and I had the big horns and 2A3 set up. If I had a neighbor kid to help me drag them down the stairs, I'd probably chance it. :scratch2:

Beautiful work here!

Wow Mickey, those look really great. Can you tell us more about which transformers you used?
