Dear All,

Just wondering if there is any news regarding the A-110-5 Tillman Oscillator, and whether there were any more details or a panel mockup available.

All the best,

Alex

There were no proceedings during the last time as our focus was and still is on the announced new modules A-180-3, A-168-1, A-157
and A-190-5. A-180-3 will be available about middle of October, A-168-1 and the A-157 modules about November. There were still some
improvements of the A-157 (much more features than planned originally and introduction of a SHIFT key, 4 function inputs instead of
only 2 ....). That's why there was an additional delay of the A-157. As soon as the A-157 is finished we will continue with A-190-5
and then some other modules (incl. more Thru-Zero VCOs).

Best wishes

P.S. Next week I'm not in the company because of a business trip

what's a Tillman oscillator ?

The main advantage are the available waveforms sawtooth and triangle. The trapezoid can be easily converted into sawtooth and
triangle by adding/subtracting.
The A-110-4 generates only sine/cosine.
