Soundlumia's Opinion

What a great decade for the legendary Heerlen tubes! You get the "textbook" Philips/Amperex Holland midrange presentation that is transparent, natural and expansive, with a slight touch of warmth that illuminates your musical world. The top end is super airy, smooth and nicely extended like one would expect from the best Siemens tubes. Vocals are intimate, sweet and forward (but not right in your face) and that always reminds me how the vocals sound on the best Mullard tubes. Bass is deep and well controlled and the accuracy feels very similar to the high end German PCC88's (Siemens, Telefunken.)

The pair worked wonderfully and sounded terrific in our professional studio setup for monitoring.

- Input: Cambridge Audio CXC V2 dedicated CD transport + Schiit Audio Bifrost 2 Multibit DAC

- Amplification: Liquid Platinum Tube Amplifier by Alex Cavalli

- Output: Focal Clear MG Pro open-back headphones

Our full tube sound review was written 100% based on the actual listening experience while this pair of tubes were running in the system described above

Measured plate current(IA): 12.6/14.97 mA - 84%/100% (100% = 15 mA)

Tube 2:

Measured transconductance(GM): 13.64/13.39 mA/V - 109%/107% (100% = 12.5 mA/V)

NO shorts, leakage or gas. NO noise or microphonics.

Appearance & cosmetic condition

We treasure this pair for its near pristine cosmetic condition - over 90% of the paint is well preserved. The identical date code of Heerlen factory etched on glass is also perfectly visible on both tubes:

DJH ⊿2C3 (⊿ = Heerlen, Holland, 2 = 1972, C = March, 3 = Week 3 of production month)

DJH ⊿3A5 (⊿ = Heerlen, Holland, 3 = 1973, A = January, 5 = Week 5 of production month)
