I've purchased above cabinet. One speaker is defect. Anyone able to determine from the serial what speakers should be in there?
s-75585
Is this a particle board cabinet?
Any other thing I should know?
Is it possible to purchase new speaker cloth so I can redo it to make it look nice again?
I do hope this is not a cabinet with a TWEETER. As that would be bad.
Thanks.

Hi Muziekschuur,
When you remove the back you can see what speakers are in it – for CTS the number will start with “137”, Eminence “67", or Rola “285”.
It is hard to tell from the picture - but the two speakers that are mounted might not be the original speakers.
As far as I know, cabinets from that time period (1974 to 1976) sometimes used particle board. It does not have a horn.
You can get grille cloth from Parts Express – not sure if they sell in The Netherlands –
go to http://www.broadwaymusicco.com/kustom3.htm (mid 1970’s) to see how the grill cloth looked from this era.
Are you using this cabinet for guitar, or for bass?
This is a guitar cabinet, but it is very easy to convert a 4x12 guitar cabinet to a bass cabinet.
Let us know how it goes…
-Les S.

Yes, these wher only made in mono form.
If you convert it to stereo what amp will you power it with?, as a amp with a tube output stage needs to be macthed for the different impeadance of how you rewire the cabinet.
Powering it with a solid state amp will eitheir cut in half or double the amps power it can put out.
A solid state amp rated at 50 watts into 8 ohms will output 100 watts into a 4 ohm load, or 25 watts into a 16 ohm load.
A tube amp will output the most watts and have the best tone when it is for example, made for a 8 ohm load and driving a 8 ohm load.
The stock speakers can handle bass for a low volume recorcding project, but for playing live they would need to be changed out for true bass drivers and 4 out of the six rear ports should atleast be closed off.
The stcok speakers roll off freuqency wise by 70 hz, a true bass driver will go down to 40hz which is whats needed to carry the low E string well in a live playing situation.
