You are bidding on a well matched quad
(4) of Mullard/ Philips EL37 Audio Output Tubes.
These are the large bottle with twin top getter EL37’s.
Philips was the parent company of Mullard
and produced some of the best tubes in the golden era of tube audio.
EL37’s were noted for their fidelity and
warmth.
This Quad has closely matched codes, 1282/MS,
1282/MB, 1282/MH, 1282/MH.
They have been thoroughly tested on an AVO
VCM 163 valve tester, with mutual conductance readings of V1 =9 mA/V, V2= 9.5 mA/V, V3 = 10 mA/V, V4= 10mA/V where 5.5 mA/V is the min good value.
The AVO163 gives a continuous reading of
both plate current and mutual conductance enabling accurate testing at varying
grid voltages.
