ASTOR AST-6SN7 Vacuum tube stereo PP power amplifier

Authentic sound without compromise: 6SN7 vacuum tube stereo PP power amplifier

vacuum tube amplifier manufacturerASTORis developing a new series with a narrower width and size down from the traditional lineup of full-size models that are heavy and bulky. This unit, AST-6SN7, is a push-pull (PP) type stereo power amplifier that has been reborn as a lightweight and easy-to-handle amplifier without sacrificing sound quality. We pursue authentic sound without compromise, faithfully reproducing the original sound source.

Two-stage structure to suppress resonance and selectable chassis materials

This machine has a stainless steel chassis. By using internal parts mounting hardware that was originally manufactured and processed, and creating a two-tiered structure, we aim to improve sound quality while suppressing resonance. The VR knobs and 10mm thick 52S aluminum alloy front panel are anodized, creating an attractive appearance that highlights the shining vacuum tubes.

Achieves performance comparable to fixed bias

output tubeIt has a self-biasing function, so you can easily replace it with a compatible bulb and enjoy the difference in tone. The self-bias capacitor used is a typical capacitor (around 100 microns), but this unit uses a capacitor with a larger capacity of 470 microns. This large capacity creates ample current capacity and delivers performance comparable to fixed bias. The sound is clearly expressed even when the volume is turned down.

Carefully selected parts and original design transformer

The transformer uses an original transformer that keeps the price down, but the sound quality is comparable to higher grade. By using carefully selected materials for circuit parts and chassis mounting parts,High-FidelityPursue. The two-tier structure prevents resonance from inside and outside, and provides high transparency without any unpleasant tastes.High-FidelityContributing to The legs are made of a combination of aluminum and rubber.

High convenience and simple connectivity

Since it has independent left and right volume controls, you can connect it directly to CD players, smartphones, tablets, etc. without a preamp.High-FidelityYou can easily enjoy vacuum tube music.
