Well, it is my final upgrade forced sale of one of my beloved Accuphase high end separates. This time it is my E-302B integrated amplifier which has 'had' to make way for my E406V. I am only selling this amp for the same reason I sold my DP-57 CD player - to pay off the upgrade debts (which are considerable and keep me awake at night :mental::mental::mental:).
Fitted with a big 700 VA transformer, the conservatively rated 120 watt (8 ohms) E-302B easily copes with my low sensitivity and power hungry 84 db B&W speakers. Sound quality is as usual with Accuphase stuff: smooth, transparent, neutral and highly detailed all delivered within a broad soundstage. Big and tank like, the E-302B's build quality is exemplary in all respects showing most manufacturers how it should be done; thick paint, solid switches, immaculate circuit boards, high quality logic controlled gold plated relays, huge Elna capacitors, engraved lettering in the casework, thick alloy faceplate, etc, etc. There are no pops, crackles, bangs, etc. Everything works perfectly. The amp's cosmetics are excellent too. I would rate it 9/10 here. There are no scratches, dings, scrapes, etc.
Very useful too is the ability to use the E-302B as a separate pre or power amp. It is done via sockets on the back and a switch. Easy. VU meters are always nice too (and both bulbs are working)!!! There are plenty of other useful functions such as a high quality adjustable MM/MC phonostage, 6 inputs, tone controls, attenuator, an absolutely superb rumble filter, two sets of speaker terminals and a biwiring option, tape copying, loudness compensation, stereo/mono switch and a superb headphone amp. Most of these controls are hidden by a lovely engraved alloy plate which pops open at the touch of a button. Being one below Accuphase's flagship integrated meant that the E-302B cost a totally outrageous £5000 in 1985. No wonder there are so few about in the UK!!
The amp comes with the original owner's manual and sales brochure.
Time for some piccies:

Look at this photo and you will see that the 'B' speaker clamps are missing. I do not no why. No worries though as the screws are just as effective and permit the use of very large diameter cable.
