Tube Test and Curve Matching

tube-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)

Resistor-catalogue

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 FilmTakman Non-magnetic Carbon Fim Resistors 1.0w: 10 Ohm

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

 

Tantalum Resistor 2W: 33 OhmAN Tantalum

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