I will add real item photo shortly.

I connected this Sherwood 2300 tuner for testing, the FM was of great sound and good working.  However, without top cover, the vintage original owner installed it in a console.  AM was not tested.  Missing the "Sherwood" name  tag in the front by the way I got it.

I owned multiple of Sherwood tuners in the past several years, this tuner had the best tuning feel, kind of the late 1970's/early 1980's Japanese Pioneer level of tuning feel satisfaction.  And this was from late 60's, it was 10 years ahead.

This Sherwood tuner was from late 1960's with a boat load of transistors.  The tuner delivered first-class super sensitivity and selectivity after a few minutes of warm up.  It had sweet rounded edge transistor sound than my highly sought after late 1980's flagship Kyocera top of line receiver and multiple Yamaha top tuners.  It also challenged to my treasured Citation 14/15 tuners at this AS IS condition.

No known issues so far, I listened to it for several days.  It had fantastic sound and performance, even through not perfect cosmetics(without top cover).  Note it was from 60's vintage, so please excuse the smaller chassis than 17 inch standard tuner receiver chassis size we have got used to.

Warning:  When buying vintage used item, the item condition is the key for differentiate treasure vs junk.  Do not fool yourself by buying another low cost unit thinking unit to unit would be the same.

Priced to go, this is a good working Sherwood transistor tuner !

Mine subbed in for my McIntosh MR77 and I'm peasantly surprised that I do not miss it after listening to the S-3300 for some time. I could get rid of my Philips 6731 and replace it with a S-2300.

Nice tuner. Most are not aware of the S-2300. The early transistor based tuners are overshadowed by the 1960s tube tuners. The S-2300 is a very good sounding tuner.

I've had offers for either of my S-3300 and nope, just not on the auction block unless someone wants to pay in the range of maybe a Philips 673 or Marantz 20b. Mine replaced a MR77 so it will give an idea as to the value I place on mine.
