Vintage Marantz 8b valve tube power amplifier
Marantz 8b Valve Power Amplifier. Become part of audio history by owning one of Saul Marantz best power amplifiers the Model 8b which together with the Model 5 and Model 9 monoblocs represent the best from the Golden age of Audio. Sensible offers will be considered. For sale my lovingly restored Marantz 8b with nothing but the best components. Chassis is in well above average cosmetic condition all mechanical parts and features are original. Used with horn loaded speakers (Klipschorns) for many years along side a companion Marantz 7c console (not for sale). This is certainly true if any restoration not modification! Is carried out by incompetent'amateurs'. All vintage equipment dating back to the Golden era need attention especially power supply electrolytic capacitors, drifted carbon resistors, leaky coupling capacitors (wax/ oil paper & di-film types). Many amps were later fitted with polyester (Mylar) capacitors which are not considered audio grade these days albeit they are not prone to leaking.

These must go as well. Ceramic capacitors in the signal or feedback paths have no business being there these days and should be replaced with Polystyrene or Mica (the latter not in equalizers) with due regard to the high operating voltage they may be subjected to in valve amps.

Polypropylene the better types at any rate! And Teflon are the choice capacitors these days albeit the choicest ones command prices that will make you squint such as the ones used in this. Unless your thing is to'invest' in vintage equipment to mothball. In the hope that in 20 years time you can sell on at a fantastic profit - good luck to you.

And enjoy vintage amplifiers, like the one for sale here, in the'present' so proper and careful restoration is absolutely essential. A further caveat is that many. Competently, use cheapo components so demand a look under the bonnet and ask questions! You wouldn't be using your vintage E-Type without proper restoration with the best original or modern replacement parts would you?

Oh and one other thing... All critical parts carefully replaced (a must-do if you are going to use it to play music it not just to admire it). Please zoom in into last three photos showing key component labels. Black Gate Electrolytics (The Art of Muse). Audio Note Kaisei Electrolytic (AN Black Gate Replacements).

Sprague Atom Electrolytics (High current valve grade electrolytic). Mundorf (Top quality Teutonic capacitors). Clarity Cap (Top quality British capacitors). Mil spec resistors as needed. Fast Recovery solid state rectification.

4 x spade to 44mm jack/banana adaptors included. Output stage is triode connected at present, changing to pentode connection is straightforward but requires soldering (so only if you know what you are doing). Independent output stage bias adjustment is simple via switch and meter. Note: Mains power 110 - 117 Vac only!

You will need a stepdown transformer for use in UK/EU. Class A Ultra-Linear 35Watt /Ch pentode 20Watt/Ch triode. 2 x 6CG7 or 6FQ7. You can check yourself approx. Package size less than 1 meter.
