Well I guess I'm getting dyslexic.
The price is $56. I bought this off eBay 2 weeks ago, but it won't work for what I wanted. GREAT unit & sound. REAL Fender !!!

Try one more time.

There should be some other numbers and letters stamped on there somewhere, Patrick. The part number (eg. 9FB3A1B) tells the impedances and mounting configuration, information that will be necessary to install it in another amp...

[Pat Moore]

Thanks Dave,
There are other numbers in the photos. It came out of a Fender amp, and I know it won't work in a Peavey.
Thanks for looking.

Those numbers in the photo are patent numbers. Like Dave said, there should be a 7 digit combination of letters and numbers stamped on the top. Without this information it's useless. There are many variations of Accutronics tanks.

Accutronics Reverb Tanks

--------------------------------------------------------------------------------

Almost all the reverb tanks that one sees for sale are the Accutronics brand. They are made by:

Sound Enhancements, Inc.
185 Detroit St.
Cary, IL 60013

Although they make many models, the three types that are readily available are a limited number of their types 4, 8, and 9. The type 4 is 17" long and uses 2 long springs, each of which consists of two springs joined in the middle. Thus, Accutronics considers this model a 4-spring unit. This type was the original style selected by Leo Fender. The type 8 is 9" long and uses 3 springs. This type is most famous for its use by Marshall. The type 9 is 17" long and uses 3 long springs, each of which consists of two springs joined in the middle. Analogously, Accutronics considers this unit a 6-spring device. All Accutronics' part numbers consist of 7 characters as described below.
1st character: type 4, 8, or 9

2nd character: Input impedance @ 1kHz
Type A B C D E F
4 8 ohms 150 ohms 200 ohms 250 ohms 600 ohms 1475 ohms
8 and 9 10 ohms 190 ohms 240 ohms 310 ohms 800 ohms 1925 ohms

3rd character: Output impedance @ 1 kHz
Type A B C
4 500 ohms 2250 ohms 10000 ohms
8 and 9 600 ohms 2575 ohms 12000 ohms

4th character: Decay time
1 = short (1.2 to 2 sec)
2 = medium (1.75 to 3.0 sec)
3 = long (2.75 to 4 sec)

5th character: Connector arrangement
A = input grounded, output grounded
B = input grounded, output insulated
C = input insulated, output grounded
D = input insulated, output insulated


6th character: Locking device 1 = no lock

7th character: Mounting plane
A = horizontal,open side up
B = horizontal, open side down
C = vertical wall,long axis horizontal, connectors up
D = vertical wall, long axis horizontal, connectors down
E = vertical wall, long axis vertical, input up
F = vertical wall, long axis vertical, output up

The following table summarizes the above data for the most commonly available units:
