Brenell Mk5M - UK Vintage Radio Repair and Restoration Discussion Forum

I am renovating one of the above. I need firstly to identify which head is which ( Erase is obvious!), markings are High Fidelity (on both), then one has R on it, the other has R-P. Booth these are o/c, tested with multimeter with a series resistor of 100K as I believe these heads will not survive any appreciable current.
Any brainwaves out there as to where to get replacement heads, preferably budget price. OK, I know you only get what you pay for but there are limits!

R/P stands for record/playback and the head can therefore be used for either purpose. The other head, marked R is used for recording only. Regrettably, these heads are prone to going open circuit thus as you have surmised they will have to be replaced

P.P.
