Circuit

• Model #: 5LP
• 20 Watts
• Class A
• Cathode Biased

Hand Wiring

• Each Rose amp is hand wired on high grade epoxy turret board insuring durability, stability and road worthiness
• solid cloth covered wire like the original (as opposed to stranded plastic coated wire) -- a must for a vintage, sweet tone
• Outstanding wiring techniques for a neat and clean look, less hum and less noise

Cabinet

Dimensions: 16" (H) x 20" (W) x 9 1/2" (D)

• Finger jointed solid pine
• Strong, durable
• Great natural resonance
• Tolex

Chassis

• High grade Stainless Steel screws
• High grade Stainless Steel aircraft locking nuts for less vibration
• Industrial quality glass filled tube sockets, no rattling noise like NOS style counterparts. Tubes can be inserted and removed thousand of times
• All grounds are done with 18 gauge stranded wire, translating in LESS HUM, LESS NOISE

Resistors  

• High quality Carbon composition, important ones are usually NOS Allen Bradley or Riken Ohm (Made in Japan) high precision, gold plated copper leads.
• Each resistor individually measured before wiring to insure exacting tolerances
• Low noise
• High temperature tolerance
• Extreme reliability
• Warm sound

Capacitors  

• High quality paper in oil or Solen Fast (made in France) coupling & decoupling caps
• Sprague Electrolytic Sprague or  CDE (made in USA) for filtering caps
• highest quality and durability
• Key ingredient to the vintage tone - modern polypropylene film caps sound too bright
• All caps are formed slowly with a variac for stability and less noise

Power Transformers (by Mercury Magnetics in California)

• Highest quality transformers made by Mercury Magnetics
• Hand wound, paper interleaved
• Period correct voltages -- no cold, harsh, high plate voltages
• Center tapped filament -- no heater hum
• Available in 220V / 240 V / 100 V

Output Transformers (by Mercury Magnetics in California)

• Highest quality transformers made by Mercury Magnetics
• Manufactured using the actual Triad engineering data
• Hand wound, paper interleaved on paper bobbins
• High efficiency
• Rich harmonics - astounding tone
• Built to last forever
• Tremendous bottom end, shimmering highs, a lot of headroom

Testing 

• Every component (resistor, capacitor, pots, etc.) is tested before installation
• Every soldered connection is tested
• Voltage checkpoints are verified throughout the circuit
• I test every amplifier for a substantial amount of time (sometimes it's hard to stop playing...) and listen for potential rattling, vibrations sweeping frequencies with an audio signal generator.

Speakers  

• Celestion AlNiCo Blue standard
