Re: Re: Sonido SFR200-8
surround is most easily rotten type ........😉 not cloth........
anyway -warranty is 3 yrs and Hungary is near enough at least to me .
I always hated that spongy type,but I must admit that in last several years I can see even durable surrounds ,much better quality than,say, one used sometimes on dynaudio drivers.
this -Sonido- surround look pretty durable and solid,at least to my 4 eyes
(btw- seeing spongy spider in Lowther several yrs ago was total shock to me ......same as almost non-existent finish on baskets.......even on basket-top magnet plate mutual plane .......)
regarding Sonidos- I heard them (in fact just one) totally open backed,without any baffle ,fresh from the box ; there is no need for any helper tweet , speed is effortless , and mid-high blend is just wow......
both cone and whizzer are made of most wooden-looking paper I ever saw . not thick,but very stiff
did I mention Cu ring in right place of choke (pole piece) ?

ps . these Iskras are just as they are stolen from Lampizator's site .......... hehe
more to come in few days..........meaning on pics of dirty drivers
seems that I''ll make at least 3,mebbe even 4, pairs of boxes for SFR200......at least one original Aion (sorta inverted hedlund) , and at least one Mau 12
but - that is job for next few months
p.p.s. pair of C45s is on the way to Mr. Varga.......for repair

How does it sound?

planet10 said:Here is another set of RCA fieldcoils. Also have chamois/leather surrounds. From the 1930s, they were mounted to a big metal bar attached to brackets on the magnets. They were driven by a PPP 2A3 amp.
amazing...
do you have any other information?
(model numbers, enclosures, paperwork)?
some other 'elderly' RCA amps in this thread-
