other upgrades

note: as of 11/1/2023 the cost of Finemet nano-crystalline core output transformers will undergo a 21% increase. this change is reflected below.

Hitachi Metals FineMet Nano-Crystalline Core Output Transformer Upgrade: Considered by Most to be the Finest Output Transformers Currently Available. ADD $2250.00

Hitachi Metals Amorphous Core Output Transformer Upgrade: Wound with Ono-Crystal OFC Copper. ADD $1550.00

NOTE: Other Output Transformers are Occasionally Available, Please Ask. Example: Now Available (1st Come-1st Served) One Pair N.O.S. James JS-6123HS (Better than Most Tamura, ADD $1500.00) SOLD, Two Pair One Pair Magnequest ($$ CALL $$).

Stepped Attenuator Upgrade: Carbon “Sweepers” as Standard (The Same Ones Used by a VERY Highly Regarded Japanese Mfg….. (Hint: Think Green Chassis). Choice of Khozmo or Goldpoint. ADD $250.00

NOTE: If the intent is to run “Source-Direct” and these are used primarily as volume controls, stepped attenuators are not recommended. In our experience, even with 48 “steps” we always seem to want a volume level “between” the steps………. go figure. ;)
