Stunning single-ended 300b amp. Known for its huge Tamura output transformers and clean, lifelike sound. Very solid, well constructed unit. I've compared the ATM-300 directly to Shindo (at 20W) and found both amps sounding quite similar but the AT had slightly deeper bass (to my ears).
Comes with stock Electro Harmonix 300bs + pair of Full Music mesh type 300b tubes
Tubes: 2 x 300B, 1 x 5U4G, 2 x 12BH7A, 2 x 12AU7A/ECC82
Output power: 8W + 8W (8Ω)
