Post pics of your builds.... - Page 180

You really have some mad perfboard skills I wish I could do something half that good.

Mine always look creepy so I am glad that they are in enclosures

thanks guys, that was all kind words.

If you're interested, all the bridges are done with a kester 245 and a Hakko 936 at 310 Celcius setting.

I'd like to try some real manly professional PCBs much later. Perfboards are realllly fun to work with but they just don't give as much performance compared to PCBs (sadly, sadly).

That is really nice work... I don't think I could do that. You just bridge between the pads with solder? Handy skill to have for protos.

^yep, just bridge pads with solder.

my 2nd millett

here is an update on the prototype amp I'm working on... sounds simply fantastic.

I started DIYing about a year ago, so I have much to catch up on.

ZVM LOD Cotton Dock
Here is a static absorber I made for my ZVM LOD. Eventually a coil of copper wire to ground would actually solve it.







CMoy
Here is the very first CMoy. Would you believe it took me two whole weeks to complete? I never did listen to it much in the end.



Along the way, a PIMETA was in the works but never ended up working. I didn't take pictures of it. I think I may have fried more than one trace.

RA-1 Clone
I have SR60s, so I figured I'd find out what the John Grado sound was really like.

Here is the first version that never ended up working. I never could figure out the layout.


Working version. Oh yeah, that's a PINT trickle charger, baby.






Alien DAC
This never did end up working. Do I have the energy to pick it up again?



Jonathan Grado SR60
"Buy low, mod high," as kramer5150 once said (I think in those words).

Thumb screws version 1.




Thumb screws version 2. This time I used a tap.


Third time's the charm.


Dynamat-on-the-driver mod.


Rescreening volume 1.


Rescreening volume 2.




Apple diyMod 4G click wheel
The caps I'm using are 220uF Nichicon UPWs, and until I feel I've listened enough to my diyMod + MHM Vol. 1 setup, I'll grab some Black Gates.

Millett Hybrid MAX
By the grace of God, I was able to pull this off. I was seriously considering pulling off a revMillett Hybrid when Colin posted this one fateful night. What amazing timing.

I'll post the different versions along the way.

It didn't work because I forgot a crucial resistor.


Here I didn't solder the input jack correctly.




Here are some extra 5.1uF Solens I bought for my RA-1 Clone. Also, 1000uF Panasonic FCs populate the boutique positions, CA2 and CA7. Not entirely boutique without a stretch, but I like how everything works together. I also received some Silpads to isolate the BJTs.






Look at that little knob. It has since been transplanted to the RA-1.


The source that I was going to use at the time.


The partspipe knob came in. Huzzah! I think I also jumpered RB14 at this point.


New tubes came in!




I present my Millett Hybrid MAX Vol. 1. I like the way everything is in terms of sound, so nothing is changing for a while. Changes are new Kobiconn stereo mini jack, RCA inputs, Toshiba 2SC3422/2SA1359.
The specs:
27.0VDC
12FK6 @ 13.5VDC
BJTs - Toshiba 2SC3422/2SA1359 @ 110mV
470uF Nichicon UPW @ CA4 and CA5
1000uF Panasonic FC @ CA2 and CA7
5.1uF Solen @ CA8 and CA9
Otherwise it's fully BOM.


Warm, fuzzy wuzzy sound.


Notice the juxtaposition of the stock Wimas on the left with the monster Solens on the right.


[edit: Spelling. *sigh*]

vixr , truly awesome work. Looking forward to seeing the final product..dB

my soha

Nice wiring work vixr . My proto is very messy due to some off-board components and heatsinks.
But who cares... it sounds amazingly good, it surpasses my MH MAX so easily... quite embarrassing to discover this .

Four dual triodes, a tube rectifier, and a big iron, 250V high-voltage supply transformer? The surprise is not whether it should surpass the MAX, but that the MAX was worthy enough that you considered the comparison in the first place.

P.S. Yes - like you, Ferrari, Vixr does excellent work!

No offense tomb... not that I considered the MH MAX in the first place for comparision.
It's just a result of extended listening test between the the amps I have built myself, accidentally.
We all have the liberty to do that in a free world, don't we ?

It's mine Guitar Amplifier Based on "Fender Twin" with some mods.

=D





It uses potted xformers! And Two 6L6 in PP-UL configuration.
