Radio Shack wall-wart and SI T-amp

[amt]

The SI supply looks to be a SMPS and will be regulated. The Samsung supply that cpemma linked, is an excellent supply and after listening to several, this one was the quietest and the one I use (when not using a SLA)

But, it comes with a 2.1mm plug. The T-amps use a 2.5mm so you will have to replace the plug or find a plug adaptor. They put out 11.8VDC on average.

Mine has a 2.1mm-pin socket so YMMV...

I'm using the UK adaptor I linked, with "2.1 x 5.5 x 12mm female barrel".

Hello everybody, here with a follow up.

I returned the Radio Shack wall wart and got my money back. Then I ordered the AC adaptor straight from Sonic Impact. It arrived today and I'm happy to say that it puts out a constant 12.25v (as opposed to RS's 14.8v).

The SI ac adaptor is nice and small, seems well constructed, and it nice and quiet.

Thanks again for all your help and advice.

When boxing up my t amp, I purchased both 2.1 and 2.5mm DC chassis sockets... The same connector I had previously used with the plastic-bodied amp delivered a comfy "correct" fit in the 2.5mm socket...

Forgot to mention that the T-amp gives off considerably less heat now as a result of the switch to lower voltage. I feel much more comfortable running it for long periods of time.

Next step is next case, terminals, pot, and if I'm brave the caps (I really want to get bass out of this thing)!

thanks again!

be carefull boys and girls i have just had my amp blown up with a wall wart this was loaned to a friend who decided to use a maplin unit
when i measured the output from this after the amps demise i found that open circuit its output was at 16.5 volts
sorry i wasnt there to supervise it before the blow up always check the open circuit voltage from the psu

Very much YMMV then, I've a pack of the various fittings from another adaptor, and the 2.5mm was definitely a sloppy fit on my 5066, the two 2.1mms I've used (on different adaptors) fitted like a glove.

Maybe it's models intended for the UK/European market that have the 2.1 (presumably the "official" Sonic Impact adaptor comes with the appropriate mains plug, voltage, etc, for the destination); did you get yours from the US?
