Thanks for Jay Lee and Thomas Tan's great review.
This Willsenton R8 is in hot sale.
Please trust that we wish to sell it at the lowest price.
But something changed, that we have to sell the R8 at a higher price.
Jay Lee make the review on Apr 4, 2020, at that time, the Exchange Rate is about 1 USD=7.1 RMB, but the current Exchange Rate is 1 USD=6.5 RMB, the exchange rate loss alone is nearly 10%, and the exchange rate is still getting worse.

The other one is Shuguang Electronic Tube Factory stopped production due to the fire hazard in Sep 2019, resulting in a shortage of electronic tubes in the market, and the price of electronic tubes has been rising.

The Willsenton factory has raised the price once a few months ago, mainly because of the increase in the price of the electron tube, but our retail price has not increased.
By January 1, 2021, the Factory will increase the price again. The main reason is that the price of the electron tube and other materials have also increased. The price increase, especially for some imported materials, has caused a shortage of accessories and increased prices due to strict inspections by the Chinese customs. The exchange rate for imported accessories is also a problem.

This Willsenton R8, since it is in hot sale, many improvement have been made.
For the packaging, the first version package is small, now it is big a lot and safer.
The Tube cage cover get better too, the finish of first verison of tube cage cover is spraying plastics, current the finish of first verison of tube cage cover is spraying plastics piano lacquer, looks nicer and top grade.

Now the price is $768.68 USD, we will Raise the price to $893.18 USD on Feb 16, and set the price to $833.18 USD on Jan 16, set the price to $800 USD on Jan 1.

We hope you can understand and support, and we are sure that the Willsenton R8 will be the best buy tube amplifier none the less at the new price.
