As described, saw this on jazzy's youtube channel & like it & thought it would be fun to make but not happy how it was packed, all the components just thrown in a plastic bag so components got all in a tangled mess, at least they could have pushed the chips into some styrofoam to protect them from getting squashed & bent legs.

To be honest, shit load of old crap , built it but as i engaged all the chips and switched it on ,, well not what i was expecting, the chips were compromised as they had not been protected properly, so all that work was for nothing 🤬 🤬 🤬 🤬 🤬

Wonderful . Brought me back memories from childhood soldering. Needs some capacitor adjustment next to oscillator to improve precision
G
I haven't assembled it yet, so I don't know how it works.
N
Everything is okay. It needs to be assembled and tested, but it looks of good quality.
L
Everything arrived as expected. Very well packaged.

Not very well packaged. All components in plastic bags placed in a plastic bag and posted. As soon as it was delivered and before i opened it i knew there would be problems. Three of the ic sockets were damaged beyond repair with some pins of the ic sockets either broken or crushed. The ics themselves were also damaged and crushed and i had to replace 3 of these also, others i was able to carefully straighten the pins without damaging the ic. The kit is a good kit and easy to build but the packaging was very poor and led to damage of components. The ic's and sockets should be at least pushed into styrofoam to avoid pin damage prior to packaging.

I haven't assembled it yet, but I trust that all the parts are there, fast shipping.
