Hi Sonny,
What the recommended transformer power would be for single transformer and dual transformer configuration.
Should it still be 500w for single transformer and around 2x 250w for dual transformers ?
So that means that 30 000 uf per rail is enough to drive the amplifier, or would you recommend 2x PSUs (60 000 uf) to allow more current
Thanks,
Oleg

For 120W:
recommend as minimum 1 pcs 500VA shared + 30mF per rail (60mF in total) .
best would be 1 pcs 500VA per channel + 30mF per rail (60mF in total) /per channel. => in total 2x500VA 2x35VAC + 4x30mF
For 150W:
recommend as minimum 1 pcs 800VA 2x40VAC shared + 30mF per rail (60mF in total) .
best would be 1 pcs 800VA per channel + 30mF per rail (60mF in total) /per channel. => in total 2x800VA 2x40VAC + 4x30mF
The capacitor is rated 63VDC.
The absolutely best capacitors is RIFA/KEMET PEH200 47000uF. But they are very costly.

Hi Sonny,
Thank you so much.
Yes, they are costly, I was looking at Kemet/Rifa's on the element14 recently.
I will get back to order the amps sometime later on this year, will need to finish some other projects first.
Do you think it might be a good idea to collate all the amp information in the first post or in a separate thread for TSSA V2 (may be joined with 1.7)
I've sent some time searching for this through the threads. Might be easier for other members too.
Thank you so much for your great work !

Hi Sonny,
A dumb question
.
In case if your PSU is used there would be kind of CRC filter right.
Although if RIFA/KEMET are used there would be just
Bridge rectifier + R + 1 RIFA/KEMET per rail right ?
Giving an RC filter only.
So filtering would be a bit simpler, but this would be compensated by the capacitor quality.
And another question, for the soft start board what kind of relays would you recommend using.
Should it be 20+ Amperese, or a 10 Amperes would suffice ?

hi TSSA v4 user,
I have own two stero TSSA v4
One is running with Dual Mono SMPS 1200400 and basic is 0.6 (A)
Another set is using tradional transformer1x 500Va,94000uf capictor
+-35 V DC ,basic is 0.8(A)
In that case tradional power supply is a lot of better than dual mono SMPS powersupply ,Bass is really huge ,tide and very clean than SMPS .
Mid and hight also more cleaner too.
My system is
DIY marten 2 speaker all are using accuton
Digital aya2 TDA1541with sd transport ,pathos endorphin CD player
Pre amp tube power amp xp2 by (John tracker USA)
Cheers

Hi MyInt,
Do you you are using straight Trafo+Capacitor Bank + Amp in the second set up ?
What kind of Caps/Resistors are you using in the power supply for this one ?
SMPS1200-400 is not the best or the ultimate SMPS for such amplifier, or in general for AB or Mosfet amplifiers. people fooled with the synchronous rectifier technology claimed, as I believe that they best serving the Class-D amplifiers mainly.
Synchronous rectifier is good to improve the SMPS efficiency, Switching at higher frequencies, (Littel bit LOWER ripple), Smaller output capacitors. but that doesn't mean its the best design / combination for Class-AB or Mosfet amplifiers nor it will give the same performance as linear PSU.
You the second person who just noticed the same thing using that SMPS with Mosfet amplifier.
Hope that helps
Hi Myint67,
Good to hear you got great sound from V4 amps.
May I know what heat sinks size do you use and how hot is it for 0.8A bias current setup? Many thanks.
Do you have experience with the fact it works better with class a or ab amps than the smps1200-400?
Many tests were conducted at AB amplifier and a Mosfet amplifier, and the sound was just perfect, deep bass. its very difficult to anticipate the results at your amplifier.
From my experience and analysis, witch is proven by three persons here, they noticed (let say) a cut off somewhere in the low frequency band.
I could offer you a SMPS to test at your gears, I am going to give you a very good deal, Just To Test! If you are interested.
