Options
Pure hand-made, the entire machine is welded with scaffolding.
Use a sq. energy transformer specifically developed for this machine.
The output transformer makes use of two top quality wideband EI output transformers.
The voltage amplification and enhance stage makes use of a 6SN7 for energy provide filtering.
The voltage amplification stage and the push stage use two pairs of 6SL7 and 6SN7 tubes, respectively.
The rear stage makes use of 4 KT88/6550/EL34 tubes for sophistication AB single-ended energy amplification.
Triode and ultra-linear choice can be found.
Exterior unbiased BIAS-ADJ present show header.
Exterior EL34/KT88 tube choice perform, simple to exchange several types of tubes, including infinite enjoyable.
Infrared full-featured distant management.
Use thick silver plated sign leads.
With pure post-level perform, it may be related to unbiased preamplifier sign enter.
Energy on mute delay perform (about 30 seconds).
Choose Japanese ALPS high-end motor potentiometer.
