2nd TW-Inspired build finished - Wow!!! + final shots

[Rimy]

just finished my second build.
wow! sounds incredible!

her name is madeleine

here are the specs:

hammond chassis 16x8x2
hammond 1650G ot
toroidal pt

v1 valvo/mullard 12ax7
v2 tungsram 12ax7
v3 tungsol 12ax7
v4,v5 mullard el34 xf3 bias @ 42ma

fast/grad switch
toggle switch for presence (4 or 16 tab)

the plexi frontpanel is not finished yet.

i will add some recordings asap.

[Rimy]

and here are the gut shots!

[El_Martin]

Wow! I like the upright toroidal

1650G has only 5k primary iirc?

Congrats on the fine build!

Ciao

Great work, very neat looks good. Any clips?

[Tubetwang]

Stunning job Rimy!!!!!!!!!!!!!!!!!

German engineering at his very very best...

[Rimy]

@el martin

the 1650g has 6600 prim
in my first build i've got the 1650h and to be honest, i prefer the 1650g.

@mcrracer

i just finished this morning.
clips will follow as soon as i got some time.

[arjepsen]

Uhm... what's holding the toroid in place?
It looks like it only the wires coming off it, that holds it...

[Rimy]

there is a 2" wide angle mounted from behind, otherwise it won't hold in place.

Nice build very good work, the transformer just throws me off a bit, I will get used to them some time.

Nice work.

I was actually wondering the other day if it would be OK to put one of those metal-jacketed power resistors on a circuit board, as opposed to bolting it directly to the chassis.

[Structo]

Very Interesting!

Do you find the noise level at all higher with the elevated lead dressing?

Those toroidal transformers always look like something out of a space ship!

Very cool and tidy build for sure.

[flood]

excellent work... or, as they say around your area... des isch ausgezeichned!

[Rimy]

thanks for all the kind words.

@structo
i really couldn't tell a difference in noise level between the two builds of mine. they are both the same, with the same tubes in it.

@drew
i've used the power resistors allready in my first build with no problems at all.

[M Fowler]

I had revisited this tread and looking at the wiring job on this amp. That is on nice job. How the heck did you get your filament wires laced together so nice.

[Rimy]

the wires are all twisted by hand. but you have to twist them completely first for all the tubes. and when you've done this, you solder them to the tubes and the small terminal you can see on the pictures.
