The HK citation 16 still eludes me. Someday one will be mine!"The legitimate powers of government extend to such acts only as are injurious to others. But it does me no injury for my neighbour to say there are twenty gods, or no god. It neither picks my pocket nor breaks my leg." --Thomas Jefferson

saved from the scrap heap of time. Wood sides. Nikko trm-50 1969? pre/amplifier
anyone got info on this beast?

OK - Mr. Ward wins. He always does ;- )
Happy Thanksgiving, sir!

That Pioneer looks solid! Nice units , are they from the late 80's?SAE C101 and Pioneer CT-F950

The Pioneer is from 1979 and the SAE is from 1985.

These units are over 30 and 35 years old and still working? That's Japanese integrity right there!

Well they work with new belts. I haven't seen any originals that the belts were still good on. Rubber dries out and cracks or reverts back to its natural state and melts into goo. -
I agree on the belts, but I'm amazed the circuitry is hanging in there.

Bing tells me after much searching this is circa 1969, 17Watts and sold for $89.00
bucks or so. You push in the bass button for a rumble filter and the treble for a
"scratch" filter.
I'm curious on how to use it as a pre? Should have taken
a pick of the back...rednedtugent wrote: »saved from the scrap heap of time. Wood sides. Nikko trm-50 1969? pre/amplifier

your best bet for arcane Japanese vintage hifi is always www.audio-heritage.jp There is also a transliterated version, too, but I cannot remember the URL at the moment (nor, apparently, can Google).
http://www.audio-heritage.jp/NIKKO/amp/trm-50.html
"Pre-amp/amplifier" may just be a moniker to indicate it's an integrated amp (and not just a preamp)? If it's not just that, there should be "pre out"/"main in" jacks on the back apron, I would think.
Nikko stuff was never common nor popular in Maryland in the olden days, so I am quite unfamiliar with it. If nothing else, they made some fine tuners (their "Gamma" tuners).

Thanks MHardy. Makes sense. I kept looking for a "pre-out" type RCA
without luck. OTOH, I read something that said the signal is split or something.
I'll try to get a pick of the back. -
I found this easy to translate:
"Preamplifier / Amplifier, which turned into all-IC other than the world's first power transistor.
The output circuit I have adopted a low-distortion epitaxial planar silicon power transistor NIKKO developed.
In addition, IC for the main amplifier driver (thick film integrated circuit), and those incorporating a resistor and a capacitor and four transistors of 13 points, has won the excellent characteristics and high reliability.
The equalizer stage of a preamplifier part, it is possible to suppress particular, has adopted the NIKKO audio linear IC, which was developed for the equalizer amplifier, it is possible to acquire a high characteristic, the ± 0.2% rate of change at -20 ℃ ~ + 85 ℃ It has been.
The tone control part has adopted two of NIKKO audio linear IC, thus ensuring excellent characteristics.
The power supply voltage, temperature compensation uses the compensation Ted varistor.
We have adopted the circuit breaker for the audio to the protection circuit.
The NW-type circuit protector UL standard (USA), has been approved by the CSA standard (CANADA), we have won high reliability.
It is the design that was unified in FM / AM tuner FAM-14 and the same size."

oh, the "English" morph of that site is www.audio-database.com
I really like www.audio-heritage.jp although it's kind of frustrating to look at and to see some of the Japanese hardware that was rarely if ever exported because (I suppose) that the marketing savvy of the Japanese companies figured the TransAm drivin', Pabts-swillin', polyester-wearin' Amurricans would never be interested in it.
:-P
You know, stuff like this:

the top speak caught my eye right away off their site.

^ Randy- I've had several of those SL-23's pass thru my collection. Nice little starter tables that usually only require a new belt and you are in business. Sounds good with the newer Shure M97xe cart.

Its got the Santon681EEE cart & stylus. Not sure if that stock/original. Cheap tt's do the job pretty good. Bedroom Carver set up.^ Randy- I've had several of those SL-23's pass thru my collection.

Workin' on a pair of Mirage L-750 loudspeakers. These actually belong to the guy who built our house :- ) A little quid quo pro.

One of the midrange drivers is borked. Temporarily, I've swapped in one of the fine old 4-1/2" pincushion frame CTS drivers. The latter may be familiar to some of you from their 1970s appearances in Polk Audio Model Nine and Mini-Monitor loudspeakers :- )
The borked MR (not a CTS):

The right speaker with a CTS temporarily installed. The CTS is actually a bit more sensitive than the original MR, so the midrange is noticeably more forward -- heh, more Altec like ;- ) -- with the CTS driver compared to the proper driver.

This item is not in Wardsweb or many others league. Very nice gear guys! I've had this one for many years. A Magnovox FD-2040, Made in Belgium, Philips CD-1 transport, I think a 14 bit DAC, metal tray (slow and clunky), RCA interconnects are hardwired (and very short). Very heavy unit compared to todays players. Still sounds good.

I am really, truly trying to de-clutter some at the old manse...
to that end, the refoaming project mentioned above has got me on a refoaming jag.
Did a pair of (Recoton-era) Advent Baby II over the weekend. Turned out fine, cute speakers but a little treble-challenged. OK, bass-challenged too. Midrange is surprisingly good, though. I am gonna invest in a pair of decent, modern XO capacitors for 'em.
But, ne'ermind. Yesterday & today, I refoamed a pair of (also Recoton-era) Advent Legacy II. Pretty uninspiring cosmetically but fairly well built -- and well worth the effort. Kind of wooly/blurry down on the floor, but raised up a bit... they're doing quite nicely, thank you very much. Listening to Black Crowes' first album as I type this (via a pretty nice hk "twin-power" amplifier that happened to also be taking up some space here) and they're very toe-tappingly gettin' the job done.
three bad photos = one decent one? ;- )

And all this time I thought you were an Irish Catholic. When did the Presbyterian conversion occur? lol
Legacy speakers were very popular back in the day, we would have considered buying a pair if we could have afforded them, even though they were not that expensive for ordinary mortals! But, when your diet consisted of tuna, canned peas and pasta, there were obviously budgetary constraints!Currently orbiting Bowie's Blackstar.!
