VSSA Lateral MosFet Amplifier

I already expressed my feelings about SMPS400A180 upgrade with Panasonic elcos in post #1053 :up:

So far the best possible PSU to supply single VSSA channel and it is uncomparable with linear PSU, so much better. Current on demand - always there when needed.

Tune-up of SMPS400A180 as follows:
- 820 uF/200 V SAMWHA replaced with 1500 uF/200 V Panasonic EE
- 100 uF/100 V SAMWHA replaced with 220 uF/50 V Panasonic FR
- 10 uF/100 V SAMWHA replaced with 47 uF/63 V Panasonic FC
- 4,7 Ohm NTC shorted after 2 s from power-up
- PSU connection wires soldered directly

Mid-range presentation lively realistic, enormous energy in low-range, even more transparent and controlled bass. :yes:

Hi LC,

Do you have the part # of those caps and NTC? It would really be appreciated. Or maybe just put them in the BoM.

Thanks

Hi guys

Yes I am receiving all the payments and carefully checking all of them.

I already answered many of you that the payments were received. Please be a little patient because there are so many mails to be send.

Before deliveries I will send info to all Proforma Invoice recipients about their payments and deliveries.

Regards, Andrej
 
I made the payment on May 3 (PayPal) and 4 days later it is still unclaimed. I will be leaving on vacation soon and I will appreciate if you could confirm.
Michael.

All payments are at the moment unclaimed since I upgraded PayPal account to business and still waiting to raise the limits. It is in procedure and will be solved in a few days. Money is there on PayPal, secure, so nothing to worry about, it is just I cannot lift it hehe ;)

Hi pinnochio

Here are the Farnell links to the caps:

-1500 uF/200 V Panasonic EE:

EETEE2D152KJ - PANASONIC - CAPACITOR, SNAP-IN, 200V, 1500UF | Farnell Republika Slovenija

- 220 uF/50 V Panasonic FR:

EEUFR1H221 - PANASONIC - CAP, ALU ELECT, 220UF, 50V, CAN | Farnell Republika Slovenija

- 47 uF/63 V Panasonic FC:

EEUFC1J470 - PANASONIC - CAPACITOR, RADIAL, 63V, 47UF | Farnell Republika Slovenija

- original NTC was permanently shorted since its 4,7 Ohm resistance doesn't limit the inrush current at all

Hopefully it helps ;)
