● Phono equalizer that emphasizes sound quality
● 2 input systems that are ideal for using 2 turntables
● Output: 1 system (MONO (L) / STEREO switchable) * MONO: L channel Input → L / R dual output
● Compatible with MM / MC cartridges (MC input: head amplifier) * MM: 47kΩ, MC: 20Ω to 50Ω
● Gain: MM35dB, MC + 22dB
* Gain can be selected according to the output voltage of the cartridge ( When HIGH / LOW) or LOW is selected -4dB (MM) /-2.5dB (MC)
● Vacuum tube: Amplification stage (V1 / V2): 12AX7, 2nd stage (V3): 12AX7, 12AU7, 12AT7 can be selected arbitrarily (according to your taste)
* The standard is all 12AX7, and if you want the smooth texture of high frequencies with a high output cartridge, 12AU7 is recommended only for V3 ( I have RCA clear TOP or Brimar to pick)
● Rectifier: Standard / diode module, option / various rectifier tubes (5AR4, 274B, 5R4 etc. can be used) ( I have LinLai 274B, WE274B, ACME 274B or ELROG 274B)

Phono + Line stage Amp (Filter - solid state diode or optional 5AR4)
Miles Davis "Someday My Prince Will Come" (Columbia / old NAB curve) 1961
"Art Blakey And The Jazz Messengers" (AES curve) 1958
Miles Davis "Kind Of Blue" (Columbia / old NAB curve) 1959
Sonny Rollins: A Night At The "Village Vanguard" (AES Curve) 1957
Playing LP with the proper curve will make a big difference in the strength of the sound to anyone listening, especially the freshness of the mid-high range,
Since the sound quality of the LP differs depending on the label and recording , the SV-EQ1616D cannot only turn on / off the roll-off (high frequency level attenuation
characteristic) of 1 kHz or more, but also can make fine adjustments when the roll-off is ON. Since it is also possible to control the tone, you can enjoy each LP with the
optimum sound quality.

Wow - i am interested as i have been looking for MC phono project. Is this an ‘all tube’ design? Is there an explanation for what the knobs do? Any indication regarding price?
More information is available on this post from January of 2019: Sunvalley SV-EQ1616D -coming soon
And more in February 2019:
SUNvalley SV-EQ1616D
I'm interested, but witholding final declaration of interest until I see the price point.....
There are 2 units
MC/MM phono EQ1616D $875
Line Pre1616D $785
If you buy both, it is $1,580.00
MC/MM phono EQ1616D $875
Line Pre1616D $785

Thanks. I’m assuming the kits are the pre and phono, correct? What is the cost of the phono kit? Thanks
Hi there - i'm looking for a phono preamp and I am considering this Sun Valley but also the ModWright 9.0. Not a fair comparison as the ModWright is much more expensive, but I'd like to better understand the adjustability offered by the Sun Valley. I understand that with Sun Valley you can adjust the turn over and roll off frequency. I do not have any pre-RIAA (eg pre-1954) records, and accordingly I don't think i have a need to use its adjustment features, whereas the ModWright has gain and MC cartridge loading adjustments which I think I would use when experimenting with different MC cartridges. Just wondering if I am missing anything regarding the Sun Valley's Turn over and Roll off adjustments and when they might come in handy? Also, other than the adjustability, are there strong features of the Sun Valley build & components that I should be aware of (eg transformer type etc) when comparing with the ModWright 9.0 (which eg uses Lundahl transformers)? I much prefer kits but want to ensure the Sun Valley is right for me.
sorry just to clarify my previous post - i'm referring to the ModWright PH 9.0 phono stage ModWright Instruments | PH 9.0 Tube Phono Stage
I am posting more photos.. You will tell yourself who is better..
This phono amp is circulating in Japan for more than 2 years in the audio community. WE listen to the feedback from hese 2 years.. .
You can use different types of RECTIFIER TUBES
With ASC 2.2uf coupling cap

Thanks for the photos - looks good.
Can I ask in what circumstances would you change the turn over and roll off knobs, if you don’t have any pre 1954/ non riaa vinyl?
