Superb explanation of what to do the reverb tank connections -- so thank you. As there are no markings as to 'in' and 'out' etc on the tank (see photos), I'll try listening with different reverb settings. Or better still I'll see if I can find a circuit diagram of the reverb tank.

Also appreciated is the explanation of the lugs and what they do. To help explain my question more clearly, I've added a new photo to try to make my explanation a little clearer.

thanks

Bookmarked, I have one these excellent amps.

Thank you so much for your quick response (and posting the links).

I had no idea RCA worked that way, so thanks for the excellent explanation.


Reverb | I probably was not clear enough, but the reverb works fine -- it was the order of the cables I was unsure about (ie does it matter which RCA jack you plug the red/black in.). From what you said it sounds like no. Any order is fine.

Photos | I found out how to upload images by searching for image upload, and it worked. Just use the attachment function.

Thanks again.

Fender Ultimate Chorus solid state amp from 1990's (130W, 240V).

Could someone please shed some light on these, probably very easy to answer questions.

1. What is the role of the tabs/lugs connecting the words from the amp to the speaker housing? 

(see links to photos) The tabs on my Fender Ultimate Chorus are both loose, and can easily be moved/removed. Not sure why it was built this way — given everything else on the amp is well made  (and yes, I will dust).





Are these tabs an electrical fitting or a mechanical fitting? (My guess is electrical, as the pos/neg terminals of the cables sit on a metal clip, which then connects to the metal speaker housing.) 

How important is it the tabs are a tight/solid fit? Will they vibrate off? Cause distortion if even a bit loose? If it is important, could I solder them in place; or is a better option to drill a hole in the speaker housing and bolt/rivet them on?


2. Reverb cables to the reverb box, does it matter which they they go on?
Are the red and black cables on the reverb box (RCA connectors) reversible? That is, does the circuitry mind which way they are plugged in? Tried both ways and it does not seem to make any difference. (I think the term for this is 'polarity'.) Just want to be sure.


3. Recommendation please for amp servicing near Geelong, Victoria Australia. 

In case it ever comes to this. (Amp sounds very good, had it for a while, but want to make sure I'm getting the best out of it.)





Thanks in advance.
