McIntosh 2105 Power Amplifier A beautiful piece of vintage McIntosh kit, enough power for every speaker I've thrown it's way, one of Mcintosh's earliest solid state amplifiers. Has been serviced and then converted to Australian voltage by Nigel over at speaker bug 🪲 105 watts into 8 ohms, equip with the signature McIntosh autotransformers In great condition, some cosmetic blemishes that comes with being an amp from the early 1970s. Sounds fantastic, demos are more than welcome! Comes with banana plug converters so you can run banana plugs into the speaker taps. Only minor downside
This AUD $3,150 ask for a used McIntosh MC2105 is fair—right in line with recent Australian sales, like a "good condition" example that moved for AUD $3,800 locally. Vintage market ranges typically span AUD $3,000–4,000 for solid units, depending on cosmetics and service history, so it's neither a steal nor overreach if truly functional.
Buyers, insist on proof of a recent recap—those 1980s electrolyptics fail hard, risking output stage damage. Verify original glass faceplate integrity (no cracks or delams) and matching serials on both channels; manual and power cord should be included, but skip unless serviced within five years. Test with your speakers on-site.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
