AMP4 picture thread

[V-bro]

Most of you will see some similarities in all my builds, but I thought it would be nice to post some pics as I've never shown any of my AMP4 amps so far...

It's simple as "beep", just a power amp with a toroidal transformer, modushop casing and an AMP4 module. No softstart (not necessary), no balanced input, just the plain amp.

I think it is beautiful in every respect...if I may be so bold to say so myself...[:I]

V-Bro,
What case is this, looks very sharp. What are the dimensions?

Vincent,

I like the glowing switch on this unit.
Where did you get this and about how much is it ??

[V-bro]

It's great! Vandal resistant and reasonably nicely priced for the incredible rugged quality they are...

I got it from Farnell for around 12Eur...

These switches look really nice. For anyone in Australia, I found a cheaper, lesser quality, copy of this switch. It looks the similar, but is only rated for 500mA @ 250V so you would only use it for switching a softstart like PSU1-SS or a preamp. I use one for my Truepath.

It's around $10 compared with appx $40 at Farnell.

Also nice one Col! If we design a latch circuit with relay we can even use momentary switches, and the choices in them are enormous!

Hi v-bro very nice job very profesional looking how does the amp 4 sound against the amp6b

[krilli]

In my opinion, the Amp4 sounds noticeably better than the Amp6. It's more of the same, but somehow more hypnotising and musical. Objectively, the distortion is a few times lower.

[V-bro]

It does indeed not only have more "balls", but it also has more finesse/subtlety. Without direct comparison AMP6 is a stunning little amp that kicks thousands of other amps straight out of the ring. Even ones that cost as much as a bunch of AMP6'es. But when directly compared the AMP4 is quite a big upgrade and very easy to tell apart in a blind listening test.

Hi V-bro.
Two questions for you about Amp 4.
1 - Looking at specs of TK2050 shows a significant difference of THD with other Tripath chips.
Do you know if it is due to more NFB ?
2 - Is it possible to use Amp4 as a balanced mono amp, i.e. with balanced input and paralleled outputs with one in reversed polarity ?
