[#2] vt25, vt25a, vt62, ux210, ux250, ux350 VT25/VT25A/UX210 belongs to 10Y family VT62 is military designation of 801A which is similar to 10Y but of higher plate dissipation The above are very small power tubes but are better used as Driver tube in preamp circuit. UX250/UX350 are type 50 tubes and not compatible with the above tubes at all. A higher power tube but still small in today's standard. |

[#4] vt25, vt25a, vt62, ux210, ux250, ux350 yes, and can also use VT62/UX210 But don't put the above tubes in an amp designed for VT62 without verifying compatibility. |

[#5] vt25, vt25a, vt62, ux210, ux250, ux350 Thank you, Is it type 50 tubes have too large power for the output transformers of vt25 amp? Ed 最後修改時間: 2017-03-28 17:50:00 |

[#6] vt25, vt25a, vt62, ux210, ux250, ux350 the difference is not just power. they are different type of tubes and should not be used in the same amp. |
