I finished building my EQ1616D phono equilizer. It worked great after first time powered on. It is still in break-in period, but my big impression about this phono equilizer is it definitely provides tremendous details. Currently I hooked it up with Sansui SR-838 (Denon MC), McIntosh MX110Z and MC275 MK VI. The speakers are Rogers Studio 1A.
I'd like to share some of my experience during building the unit. I made below upgrades.
--replaced stock tube sockets with Belton sockets
--Mogami W2314 microphone shielded cable which has very low microphonics
--replaced C1 film caps in input sector with Mundorf EVO oil
--replaced C3, C5 and C6 film caps with Mundorf EVO gold silver oil (bought 5mm male to female stainless hex spacers to increase the clearance below turnover select board in order to accommodate slightly larger Mundorf caps). It is also a good idea to put on heat shrink tubes on the two 30mm spacers supporting the turnover board.
--Takman resistors in signal paths (the stock resistors are already high quality ones, The reason I liked Takman is its wire terminal is stiffer than most other brands. It is easier for arrangement for point-to-point connection.)

I have a WE 274B on the way, just hoping to use an RCA 5u4 in the meantime. All the Japanese owners manuals I find online indicate the 5u4 can be used:
https://www.kit-ya.jp/user_data/SV-EQ1616D使いこなしガイドV2.7_20201013.pdf
'V4:標準/ダイオードモジュール, オプション/5AR4,274B,5R4,5U4,5Y3が使用可能 ※音色は変化しますが特性(ゲイン, 周波数特性等)に⼤きな差異は ありません。'
Just want to make sure I will not damage anything by using it.
I have just found out that the production from Jan 2021 the position of the PT is different from DEC 2020 production
All new production EQ1616d (after Dec 2020) the PT is position as the following photo.
There is no component changed..
