....Jozua's Ribbons made every amp clip violently and we never had a Krell...fizzing and popping like a bowl of rice crispies those ribbons were....do not play vinyl on them again,EVER....I beg of you...

Kent,

At least they managed to capture the attention of the audience....

Maybe, next time I will bring a one meter long twin ribbon DIY driver with a .5 ohm impedance but only if you promise to bring a safety belt to tie you to your chair.... then I will show you what a bit of current can do to improve the thrill capacity.

Regards

J

Why would you use a driver that nothing but a welding machine can drive - impedance of 0.5ohm is just silly....

Not trying to stir but clipping aside,the left ribbon was doing some weird stuff at certain frequencies even on the power amp belonging to Chris which I think is close to 100wpc...just trying to establish if I was the only one who heard this?Nothing more.How low do these dip in impedance?

I heard it as well.

Could be many things- no such behaviour with my 50 watt amp...

Excellent...I thought it was just me...one year behind the dancefloor bar at Raffles in Bellville has had it's effects on my hearing.

The driver is a 2" Sony fullrange in an experimental Cornu spiral built by Richard....Jozua's Ribbons made every amp clip violently and we never had a Krell...fizzing and popping like a bowl of rice crispies those ribbons were....do not play vinyl on them again,EVER....I beg of you...poor Mafioso thought someone had swopped his 301 and Supex for a Crosley with a Sanyo cart...I hope he believed me when I assured him that this was not Candid Camera(or his gorgeous table:)

Thanks, Kent. The above description is exactly my thoughts about the situation. You can see me clutching my hanky just before Joy wiped-away my tears.

Not to worry Jozua, I'm sure your toys have merit. I have a modified Einhell arc welder with WBT binding posts and Coke fridge cooling fan for a second chance to convince the unbelievers that vinyl ain't dead.

@ capetowntracks

Apologies for placing the 301 directly behind your feet. My own mistake and there's absolutely no damage.

And to all the kind gentlemen who helped me load and unload, many, many thanks :thumbs:

@ Dean

 As you saw, I do indeed believe in cables but for all the wrong reasons :giggle:

Thanks to all for a super evening.

Is this for real, or an incomplete component? Usually there's a transformer in-between to match the load.
OK... just re-read: it's DIY. So, yes: you are missing a transformer.

I do not use transformers with the 0.5 ohm ribbons.

1 - Ok, I will post individual pictures, then you can see Kent looking longingly at Joy in the front row
2 - My amp has a 120 watt pc output but the heatsink managed to get very warm driving the ribbons.  I thought it was the classical music doing it instead of the Jim Reeves number
3 - My own ribbons have a transformer built into the enclosure, but the DC resistance across the input is 1.8 ohms and it is recommended to never connect them directly to an amp
