Last night I began my journey into building tube amps by ordering a kit from (play horror music) Aliexpress. I opted for the non-Bluetooth model to simplify things and it cost me $438AU (incl. postage and sales tax). I will report back once it arrives and I start building it.
SPECS: Tubes: 6J8P x 2 / FU50B x 2 / 5U4G x 1
Output Power: 8W+8W
Frequency Response: 20hz-20khz
Output Impedance: 4 ohms and 8 ohms
SNR: 90db
Input Sensitivity: 500mv-1000mv
Input Impedance: 100kΩ
Harmonic Distortion: 1%(1khz)
Size: 320mm(L) 210mm(D) 160(H)
Caution:
Product options are kits, not finished products, you need to assemble yourself, the package includes circuit diagrams and wiring diagrams. Please install it correctly according to the drawing. Please contact me if you have any technical problems. The kit does not come with a power cord.
UPDATE: I just found this useful video series showing construction of this amp 😀

A couple of years ago I assembled an EAR834 clone phono stage. the quality of the kit was surprisingly good, but you need to replace some of the parts which were a mix of very decent to low quality. The EAR was not point to point wiring but simply plugging components into a high quality board which had the components printed on it, hence a doddle to build really. As a phono stage, it sounds amazing, especially after replacing the supplied tubes.
More recently I built Jerry Curtis’ great little SEP “spud” amp. That one is point to point wiring. What a little gem that is! It kills my A50 dead!
Please let us know about your kit and what the quality is like. There are some gems out there.
