Re: Phono Transfer System

Nice stuff ! Wayne's design and craft is definitely proven worthy. If anyone checks the original posts and original threads, (including comments with the original engineers involved !), amazingly the folks who tried state of the art FETs actually did not hear any benefits over choice op-amps. How do...

Re: What is Your Preferred Listening Perspective ?

Sorry for the double post. I meant to post this on the more appropriate Playback forum; which I think I accomplished. However, I cannot seem to edit or delete this thread from this forum. Oh well, it is an interesting topic... :lol:

What is Your Preferred Sonic Perspective ?

I am hoping this subject gets some cool responses. When you are either monitoring in the studio or simply kickin' back and playing some favorite tunes, what is your preferred listening perspective ? Surely, we are all hoping for enjoyable sound, while many of us hope for the most accurate sound poss...

Re: RIAA/Inverse RIAA Circuit - Jumper Selectable

Back to the RIAA thread, Wayne is the man ! Thanks again, Wayne for lighting this fire and putting the info on this forum ! Playback seems to be a slow responding forum. Threads either get unnoticed or the good folks might have their own "special recipes" which some may want to keep private; or so i...

Re: Wanted: Ramko Research SP-8 preamp schematic/manual

Well; no replies yet...oh well...I am patient. I did begin planning my resto attack. I confirmed that active feedback phono EQ is utilized; thankfully. I will tweak the EQ parts quality, replacing the ceramic caps with polystyrene caps, upgrade some interstage coupling caps; then beef up the power s...

Wanted: Ramko Research SP-8 preamp schematic/manual

This is an early IC equipped phono stage with tremendous gain that was a regular in many broadcast studios. I have the earliest version; no suffix after the SP-8...brown case with white/tan face including two gain controls on the front. Inside, there are a few tweaking pots, what looks and sounds li...

Phono Cartridge Choices

What a super coincidence ! I too favor conicals and the Ortofon SPU GT has been my reference since the late 1980s ! Yes, it is a valuable cart; maybe should be reserved for your fave sessions. Their diamond quality is second to none; one of my SPU-GTE was used for over 15 years on an almost daily ba...

Re: Audax N-20 Cartridge

Greetings All ! First, all Audax carts were definitely magnetic, which will require gain and proper EQ for your needs. Their first carts were the horseshoe magnet type; evolved into the replaceable styli types that actually predate the GE replaceable styli ! Plus, their styli "resemble" the GE RPX-0...

Re: Which Phono Preamps do you really enjoy to listen with ?

You know, I have one of those Acro 1001 preamps, as well. I pass by/see it every time I walk thru the mancave ! It is a very worthy preamp ! Yes; it sounds very sweet and endearing. Even though it uses a unique tube compliment, one 7247 and one 7199 per channel, it was well thought out sonically. Bu...

Re: Welcome, Newbies! Say Hi in this thread!

Tube gear can be quite reliable; especially classic 12AX7 based preamps. They require only simple power supplies and can even run AC on the filaments for phono preamp duty. Eventually, or sooner, I'll be writing about them in the "Playback" forum and posting some schematics in the "Schematics & Circ...

Re: changing cartridge for audax tonearm?

I have that arm, too. The long one, KT-16 is very good for a mono setup and okay for stereo as well. If you want solely a mono cart, I highly recommend the GE Variable Reluctance model RPX-050, known as the Triple Play with its' red knob atop the arm. That small round "cover" on the golden Audax hea...

Re: Which Phono Preamps do you really enjoy to listen with ?

All right ! This forum seems slow for replies; so, I'll reply with more ranting. I don't use the Dyna PAS any longer. It was simply a convenient mainstay in the very early 1980s, until I graduated to an Audio Research SP3A; then a hard to get Paragon E. That Paragon E is probably my best sounding Ph...

Which Phono Preamps do you really enjoy to listen with ?

Hi all ! I am new to the society but have been actively involved with tube preamps and tube amps for more than a few decades. Starting out with an intense interest in hifi in the early 1970s, caused by my older brother's Dynaco ss gear, my first system had to beat his. So, I auditioned oh so many br...

Tubes! Welcome tubeactive

Hi ! While this is my first post here in this secret society, I am not an audio newbie. I first learned of this forum while researching the Gotham PFB-150 Cutter amp. I have been lurking now and then for a while. It was actually difficult finding real lit on this amp's innards. Thank You, Steve E fo...
