Holdt for ett år siden på å kjøpe en SA 250 Mk IV, så vet du litt om hvor på treet du er med MkII.
mvh
Når det gjelder alder så trenger det ikke være mer enn to år forskell mellom en SA 100 mk2(som gikk ut av programmet i 1997) og en SA 250 mk4 (som kom i 1999)
Jeg har selv eid en SA 100 mk2 inntil nylig og syntes det var en meget god forsterker. Tror ikke du trenger å bekymre deg for alderen og varme. De fleste jeg kjenner som har eller har hatt denne forsterkeren kjører de i kl AB 95% av tiden, siden det er så greit å skifte klasse på fronten under drift. Dermed er kjølearealet solid overdimensjonert 95% av tiden. Da blir den ikke lunka en gang.
Dette sier litt om hvor du er effekt og kapasitetsmessig med en SA 100/102(som jo er siste utgave, kontra en SA 250 mk4:
The PLINIUS SB-300 is our answer to the perennial power versus sonic quality debate.
We were approached about 12 months ago by a Californian company engaged in the manufacture of large home theatre speaker systems, and asked to submit an amplifier for their appraisal.
There were two important specifications that had to be adhered to, a, the amplifier had to sound good, and b, the amplifier had to sound good at 120dB!
We sent them an SA-102 and goal one was achieved. The sound quality was better than anything experienced previously however under rigorous testing they found that the SA-102 would deliver 115dB prior to clipping.
We then sent an SA-250/4. Goal a and b surpassed but the SA-250/4 is very large and a little too expensive for the multi-amplifier applications they had in mind.
Back to square one and some head scratching. Our design team decided that we needed a 300-Watt, SA-102 package and this is exactly what the SB-300 is. The basic circuit topology is the same as the SA-102 but with a larger power supply and more rugged output stage. The number of output devices is double that of the SA-102 and the two toroidal transformers are larger.
The SB-300 operates in Class AB bias and as such the standing temperature is lower than that encountered in our SA series designs.
