RCA 9289 tube amplifiers


The RCA 9289D was the final version of this great 200W amplifier.  It features four 6550 in the output stage and an interesting power supply with OD3 regulators.  My father designed the final version of this amp for RCA and we have several available.  I'm testing the water to see if there's still a market for this excellent amp before I start recapping them, or whether folks would prefer them bone stock.

i agree w Ralph unless you have a significant non refundable deposit from a client making the individual component selections....

please do keep us apprised of how this all turns out..

@hilde45  there is your Orange drop answer, i may....have dated myself....

@tomic601 Thanks. I don't know how many "orange caps" there are out there. I'm replacing mine with Mundorfs and if it goes south, I'll change them back.

@tomic601 and @hilde45 are you guys telepathically linked? 😁 I see no posts from Hilde in this thread about orange drops? And as usual great answer from Ralph.

@jond sort of..I mentioned in a thread Hilde started that i ( and others ) had been rolling caps as tweaks way back when Sprague Orange Drops were a " thing "...I thought it amusing Ralph weighed in here....

back to the music....

One of my employees refurbished a pair of the little brothers to this amp, that he got from an old theater. IIRC they made about 60 watts using a pair of 6550s.
