The unit is what I expected. The only issue was one of the capacitors had fell off in shipment. It is labeled EC1. An easy repair. just giving a heads up to supplier.
I assembled this kit in about 1 hour. It works perfectly once the bias current is set correctly. BUT!!! I will not buy from this store again for several reasons. 1. The FET that was supplied as new, was in fact used, it was covered in solder, and in poor condition. 2. Delivery was terribly slow and the tracking information was just lies. Even though it has now been delivered, the tracking says it is still in transit. 3. Contact and support from the seller was no help at all. 4. All my other orders from Aliexpress are also lost in transit, I might not buy from China again unless the service can be improved.
