The FU25 is the same as the US 807/VT136. It is a 60Mhz transmitter tube with a 600 volt anode. 25 watts. $10 each new from the Saratov factory in Russia.
Impressions of the FU25/1625 Tube in an Amp???
Just as the title asks, I am looking for peoples impressions of the use of the FU25/1625 power tubes for use in HiFi amplification.
From what I gather, these are essentually a 12 volt 6L6GC with 30 watts of dissipation and sound like the 300B. I'm considering the Musical Paradise MP-402 that uses four per channel to get 75 WPC.
I know it's "Chi-Fi" but some is well made with quality parts as would be used in a high-end brand from elsewhere. Some of this stuff punches way above its weight class..., which in this case is about 64 pounds. Hard to beat the price for the power if it sounds good.
