A perfect Amplifier 6c33c Single-ended parallel Class A Monoblock

This auction is for a set of monoblock using 6C33C tubes





















This monoblock is 100% made in USA by Lansing Audio Co. based in California. By using 100% natural wood and golden inox 24k has done this monoblock a classic but elegant look.

Each side of the monoblock is large with dimension 25,5 inch x16,5 inch (65cm x 43cm). Because the 6C33C tube is a triode tube that has low impedance. So during the assembling process, I have tested the sound quality of the product many times over.



All the power transformer, output transformer and choker are ordered from Calassic Tone address: Magnetic Components, Inc. 9520 Ainslie Street Schiller Park, IL 60176















with specification that’s meet the requirement of the 6C33C tube. All the wires inside the AMP are silver coated. The coupling capacitors and capacitors of the preamplifier board are ………….. Also, all the source capacitors are Nichikon’s capacitor from Japan. Operating voltage range from 110v – 230v.

I designed this monoblock based on parallel SE board diagram so it’s power could reach up to 50W which delivers a 98db sound quality; even if you have a lower quality speaker, this monoblock could still delivers excellent sound quality. I added a customizable ohm of 4ohm, 8ohm and 16ohm to fit your speaker’s specifications. (Function zero feedback or lowfeedback (- 10dB)) And also a converter to switch from amplify mode to power mode so you can use it with or without preamplifier

This pair of monoblock is designed to handle most type of music and also many types of speaker like Altec Lansing A5, A4, JBL, TAD… . I assure you that you will not only satisfied with the sound quality that this monoblock delivers but also the elegant design of it. I assembled this taking care of every little details so you can be assured of my product quality.

This monoblock is large so we also offer a set of holding frames designed for them. If you are interested in buying the holding frames, feel free to contact me or visit my ebay shop.

LANSINGAUDIO introduce to you this
ultimate parallel Single Ended Mono Block
Power Amplifier 6C33c-Se. High output
power Mono Block 6C33c-Se can easily
drive electrostatic, magnetostatic or
standard dynamic type of loudspeakers at 4- 8 and 16 ohms. New generation of hand wounded output
