Product only includes PCB board and the components on the PCB board, without the tube
KITS require you to weld yourself.
This kit does not include valves and output transformers.
Adopt imported resistor, Philips high voltage capacitor.
Cathode capacitors are Panasonic with warm sound. Coupled to VIS BC high voltage capacitor, the sound match is very good.
If you want to make it cheaper, you can use 6P3P for EL35 and 12X7 for ECC88. However, the power of 6P3P is lower. In fact, if you want more power, you can use KT88 instead, just adjust the cathode resistance.
Product details
This circuit uses 12X7(or higher end ECC83) as voltage amplification, noble EL34B as single-ended class A output, rectifier part does not use the low efficiency of the bile rectifier, bile rectifier, a few elements of a rectifier tube and tens or even hundreds of rectifier tube sound difference is very big, here uses Philips rectifier tube plus field tube electronic filter, In this way, the overall background is quiet, the extension is very excellent, and the XYAS gold series E0049+E0011 speakers used to promote their own are very excellent.
PCB size: 170x99mm
Transformer voltage :230VX1 (can range from 200V to 250V, greater than or equal to 300mA) 6.3VX1 (2A current)
Packing list
1PCS EL34 Single-ended Tube Amplifier Board DIY Kit
(NO Tubes)
Pictures
Because BC capacitor 100U has been discontinued, the BC-100U-400V in the original picture is replaced by Japanese black gold steel brown 100U-400V of the same grade, please note
