Case for Helder's TA2020 MKIII Amp Module

[kickngas]

Are there no American suppliers with "nice looking" enclosures? I have searched and found several suppliers, but mostly, they are butt ugly. Anybody?

For the nice looking case in Ebay, I read this:

"Import duties, taxes and charges are not included in the item price or shipping charges.
These charges are the buyer’s responsibility.
Please check with your country’s customs office to determine what these additional costs will be prior to bidding/buying."

How much could a US buyer expect to have to pay, if any?

i went with the SMPS from Helder, and the case suggested by kickngas here. Everything should fit although it will be tight. I probably wont install the input selector.

Are either of you guys going with the tube buffer at any point? I will probably wait until after I get acquainted or bored with the ta2020 amp before I make a decision on that, but it sure looks good, and supposedly makes the amp "smoother" sounding.

@Saudiof,
I checked the measurements of the ta2020 and the smps, and I do not think they will fit into the case you mentioned. You may want to double check!

Do you think my power supply will fit? No! just kidding.

This is my "hack" spare parts power supply for my T amps. The transformer can deliver 50 amps at 12 V! The rectifier bridge is over 5 amps, the filtering caps are 12,000 uF each @ 80 VDC surge, the only choke point is the in-line regulator on the CPU heat sink at 3 Amps. The orange drop .1 uF cap is suppose to help transients response (according to the spec sheet).

My TA2024 amp draws about a max of 500 mA at almost full volume on some bassy transients.

Have I noticed a difference between it and the laptop power supply that came with it? Yes, very subtle but very nice, better bass and better airy extension of the highs, but again, very subtle. Worth the effort, but maybe not worth the cost of the parts.

Anyone have a case to recommend for it?

This is like fitting a V12 engine in a Smart Car.

The case is 20.3 x 14.5 x 6.9 cm.

The pcb is 11 x 7 x 5 cm

The smps is 11 x 8 x 3.6 cm

Appropriately placed, the pcb + smps occupy 15 x 11 x 5 cm

Clearance on the side is 14.5 - 11 = 3.5 cm

Clearance front to back is 20.3 - 15 = 5.3 cm

Clearance on top is 6.9 -5 = 1.9 cm

It's tight but I think it will work. If I made a mistake it's already been shipped so I'll use it for something else. The Taiwanese case has 1 cm vertical clearance, hope that isnt a problem.

I have a tube preamp (also a headphone amp) , so I will try using that and wont be buying the tube buffer initially. I use it with a Charlize t-amp and it sounds good

Whaleman,
Looks like you will need a milk crate for that monster! @Saudiof, looks like it just might fit after all. With input and output connectors, it will be standing room only for sure!

Whaleman,

The Home Depot and Lowes have some utility boxes in the electrical supply area that may fit the bill.

What speakers are you guys going to be matching up with the ta2020? I will be using some Madisound Vifa recession busters. Sort of low efficiency for the amp, but I will see.
