Hi All

I have regular requests from people looking for parts for their DIY tube amp projects. Output transformers seems to the hardest to find at a decent price. While scanning the web, I found this item at RS

5.6kΩ: 4 Ω/8 Ω/16 Ω, 25W Output Transformer for EL34

    RS stock no. 123-7237 Mfr. Part No. V78A01F Manufacturer OEP

R1237237-01.jpg


The specs are as follows:

V78A01F 25W valve output transformers are constructed with a grain orientated steel core. The core construction reduces distortion and reduces the stray magnetic field. Featuring 24.5% UL taps on the primary output these push-pull transformers have outputs for 4 Ω, 8 Ω and 16 Ω. V78A01F push pull transformers are suitable for use with amplifiers with EL34 valves.

UL94-HB (minimum)
Temperature class B (+130?C) minimum
19 H total primary inductance at 1 kHz
85.7 mH total secondary inductance at 1 kHz
Isolation of primary to secondary is 1 kVrms for 2 seconds

Do you know of any similar products available in SA?
