Default Complete amplifier kits

Hello guys,

My first post in amplifiers forum.
Are there any complete SS amplifier kits available, and I mean complete, including PCB, all components, transformers, enclosure, you name it, without need to do any measurements, transistor matching, etc., all you need is soldering iron and screwdrivers?
And if such kits exist, how do they compare to the commercial offerings, what bracket would they fall in?
I think good analogy would be the speaker kits from Wilmslow Audio, I have ordered Prestige model, it is essentially complete kit with exceptional drivers, cross-over on PCB, pre-cut MDF pack for cabinet, this kit is in reality comparable to very good commercially available speakers in range of $10-15K.
You can see details here: https://secure.wilmslow-audio.co.uk/...4500ac55997a6d
So is there an amp kit that would be comparable to this speakers kit in terms of performance?
By reading this forum I got impression that there was no such thing, you really need lots of equipment (oscilloscope and precise measuring equipment for example) and knowledge?

Ampslab has got some kits.
Some come with heatsinks, other without
The Bi70mk2 for example could be an option. Includes heatsinks.
http://ampslab.com/bi70mk2.htm
Looks like it is Out of Stock ..... contact Michael Chua

You need to buy the Transformer 2 x 30 VAC, minimum 150 VA.

You will hardly not find any amplifier kit, that includes transformers.
But if you follow the recommendations, you will easily buy those.

Siliconchip in australia has got some good kits:

If you want some easy build kits using Power Amplifier IC, Chips
Try http://www.chipamp.com/orders.shtml

COMPLETE kit with everything included, but its 240V trafo
Its even with drilled heatsinks
It seems all you may need to find yourself is some wire and solder tin...in the old days LC Audio even delivered that too, but SKA may deliver that too, on request

AU dollar is cheap, and his things are on hand very reasonably priced

"Siliconchip in australia has got some good kits:
SiliconChip Amplifier Projects & Kits - Lineup"

Silicon Chip magazine designs the amplifiers and other kits.
Altronics is the main supplier of complete kits,including screen printed metalwork.

http://www.altronics.com.au/

Jaycar also sells a variety of short form amplifier kits from Silcon Chip magazine.

http://www.jaycar.com.au/

Many of these kits are based around the the "Blameless" designs of Douglas Self, or use similar topology. They are all claimed to be of very high performance.
See elsewhere in the forum, the thread about the Silicon Chip ULD2 amplifier.

Hello SashaV,

The Wilmslow Audio looks like a very nice project.

An option for an amplifier kit could be our SPA550 Kit.
I think the Prestige model deserves at least 150W at 8 ohms when passive driven.

Why not go active now that you have the chance?

Thank you guys for suggestions.
Robert, I will eventually move to active, for now it will be passive.

The GT-101 is a complete amplifier kit. Just add solder and some assembly time.
