yes, one soft start can be used for multiple transformers.
Use a small TxA fuse on each transformer supply.
And a larger TxA fuse at the mains incomer of the amplifier.

Halo
Just to give you some ideas
below are some pictures of a Sympatico amp I am building for my father.
I have used one 1000VA 2x25V transformer to power 2 channel
you can see a little circuit i put together to distribute the +24V, 0V and -24V rails to each amp & also included a thermistor for trafo mains & earth
box is simple MDF panels glued together, perspex top panel will follow and nice gloss finish will be applied

Like Arne i am still waiting for round one boards.
If i stump up the dosh for another lot will they suffer the same fate ?
I've updated the wiki for round one. I guess i'll just put it down to Experience.

BPA300 Kits
Kits
The Pricing for kits has been drawn up.
To populate;
2 Boards = £83.50
4 Boards = £167.00
Becuase of the exchange rate at the moment, this works out rather cheap for anyone in europe or america.
As i am going to be ordering from a UK supplier, i am going to have to ask everyone to pay me in GBP (British Pounds).
Could i just have a quick hands up on people wanting kits? I would like to get all payments the first half of this week. I have other things i need to move on to.
Components;
I have included nice parts, without going over the top on what is necessary, after reviewing the design of the amplifier.
Resistors = Multicomp / Vishay / Panasonic
Trimpot = Bourns
Film Cap = Mundorf MCAP
Capacitors = Panasonic FC Low ESR
Everything is included to complete the amount of boards you require.
Kits will be ready a couple of days after all payments are with me.
As this is a rather large amount of money, i would prefer if people were paypal verified.
If people want insured shipping, courier shipping etc let me know.

Forgot to add, i will be including a construction guide with the kits. Everything will ship as one package so you are ready to get building!
Parts will be in anti static bags etc. I will also label everything with part numbers and values.
