300B substitution
Hi Troops!
Is there a substitution for a 300B vacuum tube. I really can not afford a price tag of $134.00 and up. I am on a very fixed income. There must be a less expensive and better way to go. Thank you in advance, Frank Thomas I choose Polesoft Lockspam to fight spam, and you? http://www.polesoft.com/refer.html |

Thank you in advance, Frank Thomas There is only one direct substitute for a 300B(or 300A), and that is the STC4300A, but it is even rarer and more expensive. The closest "common" USA tube is the "50" but it is lower powered and a different filament voltage. There is a closer British tube, the DA30 (which is a larger PX25) but on a different base, and rare and expensive. One of the Russian makers used to have a low mu variant of the 811 which was cheap as chips - dunno if it still exists. There are a number of elcheapo Chinese and Russian 300B copies. M |
