Bought a different version of the low cost DIY tube buffer kit to try.
The new toy uses two Chinese 6J3 tubes, with option of US made 5654W(s). My initial purchase was with the default Chinese made 6J3.
|Initial kit purchased|
|Similar layout to the previous kit but with more space for swapping the critical capacitors|
|Uses non-mainstream EC capacitors on the PCB|
|The default 6J3 purchased with the kit|
|Assembled kit in-action|
This new kit has the same power requirements and input-output layout(s). However, the output volume for the new kit is much lower than the previous. The potentiometer output is even at low volumes and cames with a volume knob which also functions as a power-on/off switch. To enable more space on roughly the same footprint, the new kit uses SMD resistors which were pre-soldered onto the PCB.
How does it sound?
Best way to describe is as if someone enabled a "tonal normaliser" on the output😬.
When I contacted the seller, they assured using the US made 5654W would make a "night & day" difference. Many online reviews does mention the US made 5654W(s) are worth the upgrade. Thus I placed an order for a pair since these did not cost an arm or leg!
Will update next month once I received the 5654W(s) and give them a spin.
