You're welcome prowler. Here's a quote from the Dr. Z site. "8 ohm speaker plugs into a 1/4" jack so it's easy to plug in a speaker cable to power a different speaker."

You mean I could have found that info out for myself?

The weber in my Mini Z measures 4 ohms. My 8ohm celestion measures 6.8 ohms on the same meter. Is my meter broken or is the mini really using a 4 ohm speaker and Dr. Z is merely telling us that the tranny in the Z can handle an 8 ohm load without a problem?

Sorry for the mistake on the 8 ohm 1/4" jack statement.
The Mini is a 4 ohm load with a 4 ohm 8 " Weber Speaker.
Glad for forums like this to have a chance to correct mis-types.

Thanks, dude! By the way, I like this amp so much I'm the one who sent you that email last week about it... Thanks for making this (and my Rt 66, and my Ghia, and my z28...)

Does this mean I really shouldn't be plugging it into my 8ohm ZBest cab? Or can the tranny handle it? (I do this alot)

I'm wondering the same thing now. I used to plug my old Mini into 8 ohm extension cabs all the time.

The general rule of thumb is that you can go to a *higher* impedance without damaging trannys, but not a lower one. I don't know if Dr.Z has a different recommendation.
However, I personally notice a different *feel* to the mini-z when I plugged it into 8 ohm cabs, and I like the feel of the 4 ohm resistance much better.
So of course, I poked around where I'm not supposed to and saw that inside the chassis there is a green wire coming off the OT that is taped-off and goes nowwhere. Methinks this is a secondary tap with a different ohm rating. If it is an 8 ohm tap, I'd be stoked to put in a second speaker out to use my 8 ohm cabs with the "right" feel.
I'm pretty sure this is a Heyboer OT, anyone know if they have a conforming pattern--like "the green OT tap is always 8 ohms... " ;-)

No, that is correct higher is always OK. However, I personally notice a different *feel* to the mini-z when I plugged it into 8 ohm cabs, and I like the feel of the 4 ohm resistance much better.

Yes that is a 8 ohm unused tap. I'm pretty sure this is a Heyboer OT, anyone know if they have a conforming pattern--like "the green OT tap is always 8 ohms... " ;-) Also yes both trannies are Heyboer. Z

I assume that all you would need to do in order to hook up the 8ohm tap is install an additional jack & connect the green lead. As for the ground, could you just install a jumper wire off of the existing ground and bring it over to the new 8ohm jack safely without destroying anything? Sounds like it would work as long as you didn't hook up both outputs at the same time.

Dr.Z, thanks for the response! Prowler, getting the second tap on there as you suggest is exactly how I would do it.

Now here is the dilemma. Since the Mini is no longer in production do you mod it or leave it in it's stock configuration?

Ok, my question is, if we connected an 8 ohm speaker input and ran the amp into the Zbest (8ohms) is there going to be a level difference (louder or quieter) than running the 4ohm amp as is, into the Zbest as I often do now.

I think it would depend on how efficient the speakers are. I'm going to have the 8 ohm tap installed for sure.

Let me re-phrase that, with the ZBest (V30-G12H30) will the mini level be different running into it at 8 ohms than it does at 4ohms?

Would it be worth it to change the tap from 4 ohms to 8 ohms if you were going to use the 8" Weber at the right ohmage?
I'm buying a new Weber for my Mini, so I'm wondering if I should buy a 4 ohm speaker and run the amp stock or run the amp at 8 ohms with an 8 ohm speaker (same model speaker)

The speaker in the Mini is a 4 ohm not an 8 ohm.

I kno, but I'm getting a new one. I'm wondering if the new one should be 4 or 8 ohms, since the Mini can run on either

If I were you I would have the 8 ohm tap installed as well. Then you can use either a 4 or an 8 ohm speaker.

So I have a 16ohm Orange cab with 4 V30s -- does that mean that I can plug the Z into it?

I may be completely wrong here, so bear with me I believe that won't work, because it would draw to much current from the amp and damage it and/or the tubes. If you rewired the cab to 8 ohms (parallel?) and used the Mini's 8 ohm tap, that could work. Please feel free to correct me, anyone who knows better than I lol. P.S. I ordered a Weber Alnico Singature 8" at 4 ohms to go into my Mini....I'll update when I get it.
