Tube Test and Curve Matching

Do you want a perfect matched-pair or a perfect matched-quad?

Does your amp need tubes within a certain bias arrange or plate current range?

Get what you need. Check the test results and the curves before buying. Quote the tube number when you place an order. We will serve it for you but it’s first-come-first-serve.

300B etc. are done, other tubes will follow.

Catalog (resistors)

Kiwame Carbon Film

These are an excellent match for Hi-End Audio. Kiwame resistors are from Japan and characterized by lower noise than metal film resistors and a more natural sound. There is a growing enthusiasm for these carbon film resistors because they recapture the vintage tube sound without the drift of carbon comps. They are also very compact given their wattage rating. The resistance material is carbon film with coated silicon and finished in green.

750 volts DC max
Error Ratings: +/-5% (actually +/-0.5%)
Insulation Material: Silicon Resin
Body Size (DxL): 2W 4.2 x 12mm , 5W 9 x 24 mm

2w $1 each, 5w $2 each

Takman Metal Film

The resistor we’ve been waiting for — nonmagnetic, music friendly materials, reasonable price. More precise and sounds brighter than carbon film.Takman Precise Metal Film Resistors

Takman Carbon Film

The resistor we’ve been waiting for — nonmagnetic, music friendly materials, reasonable price. Warmer and more relaxed than metal film.

AN Tantalum

Sweet mid-range. Available 0.5w and 2w. $4.4 / $12.8 each.

10w & 30w wirewound resistors

12″ tonearm (Opera T1288 )

Specification:

Mounting distance arm base	290mm
Tonearm length	12’’
Overhang	16mm
Offset	22 degree
Cartridge weight	3-15g
Down force range	10-35mN
Armtube made of carbon-fibre carbon-fibre

Note: Damping oil is optional to adjust the tastes of the tonearm. If you like to use damping oil, you need to source them (silicon oil or silicon gel) locally because liquid is not allowed to ship by air.

Special price : $650
